Abstract:
Islam has taught to maintain relations with non-Muslims and pay their dues despite differences of faith. But the Quran also instructs not to have relations with non-Muslims. There can be misunderstandings, so it should keep in mind the circumstances in which these verses were revealed. The concept of jihad in Islam has been distorted by the enemies of Islam. The Qur'an says that no one can force anyone to accept Islam, nor can we declare war on any country just to force him to convert to Islam. The Qur'anic injunctions in this regard are clear. Islam only commands non-alignment with those who abuse Muslims and try to eradicate them. Islam commands non-Muslims to be kind and compassionate towards Muslims in contrast to this attitude. Therefore, it is not correct to call the attitude of the Holy Qur'an towards opponents and enemies as a general attitude towards all non-Muslims, because the Holy Qur'an itself commands the treatment of neutral non-Muslims. This article reviews to keep an eye on the palace and the background of the verses in which it is commanded not to have relations with non-Muslims.

Abstract:
This article systematically examines how Qur’anic legal verses (ayat al-aḥkām) have been implemented in Indonesia’s formal legal system between 2010 and 2024. Using a Systematic Literature Review (SLR) approach guided by the PRISMA 2020 protocol, nine peer-reviewed journal articles were selected from seven academic databases. The findings indicate that the legislative reception of ayat al-aḥkām varies significantly across legal domains. Economic law shows the most structured integration, with verses on zakat, riba, and halal consumption codified through clear statutory instruments and supported by functional institutions. In contrast, criminal law provisions—such as hand-amputation and public lashing—face hermeneutic reinterpretation and procedural constraints, limiting their operational impact. Family law demonstrates interpretive adaptability, where issues like polygamy and inheritance are mediated through maqāṣid-oriented readings and legal safeguards. Rather than static injunctions, these verses exhibit a living character—negotiated, reinterpreted, and embodied within contemporary legal and institutional settings. Across domains, Qur’anic legal norms “live” through contextual engagement with doctrinal consensus, institutional readiness, and political feasibility. These findings reaffirm Indonesia’s dynamic and negotiated approach to Islamic legal integration, suggesting that future Qur’an-based legislation will depend as much on contextual alignment as on textual authority.

Abstract:
In Pakistan’s constitutional dispensation, the Federal Shariat Court (FSC) is empowered to ascertain the invalidity of laws from the perspective of Islamic injunctions. The paper problematises the constitutional authority of the FSC by exploring the process of Islamisation of the suit for restitution of conjugal rights (RCR). The RCR was grafted during British colonial era onto Muslim personal law (Anglo-Muhammadan Law) as applied in Indian subcontinent. This has recently been held by the FSC to be in consonance with injunctions of Islam. In this background, the paper raises some questions as to the jurisdiction of the court and how that jurisdiction/authority is exercised. It posits that the “default legal system” is placed at a privileged position and its Islamic validity is presumed to be well established, unless it is questioned on the basis of definitive verses of the Qur’an and unequivocal sayings of Prophet Muhammad (peace be on him). It is the outcome of this judicial approach that the FSC has sanctified from Islamic perspective an instrument (i.e., RCR) that is peculiar to the Christian ideal of monogamous and indissoluble marriage, without having any plausible foundation in Islamic legal sources.

Abstract:
T?be?n and Taba T?be?n strived hard to prevent any kind of debate based on the color and differences of debate, following the path of the Sah?bah (may Allah be pleased with them). This series of tafs?r of the Holy Quran continued with all the changing requirements of the time and the commentary discussions of the Holy Qur'an. The status of Tafs?r also gained a prominent position and the status of permanent knowledge. According to the order of the Holy Qur'an, every verse of the Holy Qur'an began to be interpreted and the publication of Tafsir Ilm-e-Tafs?r started from almost here.
 The most basic source of Qur'anic commentary is the Holy Qur'an itself. Prophet? was the first commentator of the Qur'an. The character of Muhammad?, his method, Sunnah and habits are all part of the interpretation of the Qur'an. The Prophet? has clearly described the issues facing the people of that time.
 Similarly, the special thing in Qazi San?ullah's book ‘Tafs?r Mazhar?’ is that in this book he discusses the topics of the sciences of recitation and tajw?d, recitation continuously, Shazah and other recitations in great detail. Also included are important topics such as lexicography and derivation and grammar discussions, commentary on the inter-verses of the verses and verses, and the revelation of glory and the jurisprudential discussions of the verses. It is needed to compare the jurisprudential discourses of the Qur'anic verses between these two commentaries and present their merits together so that the seekers of knowledge can benefit from the merits of both the commentaries. Consequently, in view of this motive, a quick work has been chosen on this regard, because this article cannot be so thick as to give an entire comparative overview of these interpretations. A comparative look at of the jurisprudential injunctions of Surah At-Toubah between Jass?s and Tafs?r Mazhar? might be performed below the identify.

Abstract:
Imam Abu Bakar AL Jassas Al Razi is one of the Prominent exegetes and legal theorists who occupy a distinguished place among Hanafi jurists. He was born in 305 AH and remained a famous Hanafi Legal expert in Baghdad. He wrote a commentary on the Qur'an entitled Ahkam al-Qur'an (The Legal Rulings of the Qur'an) with emphasis on the verses having legal importance. This commentary deals with the deduction of juristic injunctions and rulings from the noble Qur’an in a systematic and methodical way. This research is basically a discussion on AL-Jassas's methodology of deduction of rulings from the Holy Quran with special reference to the principles of Islamic Jurisprudence he used in his commentary on the Quran. The research is a focused study of some important Qawaed Usooliyyah he has applied during his discussion on the various rulings he derives from the Quranic Verses. This study proceeds with an introduction and short biography of Imam Abubakar Al-Jassas followed by an explanation of the general methodology he adopted in His Tafseer. The second part of the study focuses on some important Qawaed Usooliyyah applied and discussed by the AL-Jassas. The last part of this study consists of the conclusion and findings of this article. The study found that Al-Jassas has discussed most of the Qawaed Usooliyyah either explicitly or explicitly and applied them in the process of deduction of rulings from the Holy Quran. He has also used some Qawaed Usooliyyah which he derives from the different verses of the Quran.

Abstract:
Islamic teachings explained us everything related to our lives in the light of Quran and Sunnah. Some of them are specified for Muslim women like feeding baby, abortion, Iddah and veiling etc. Veil is the most important part for Muslim women in their lives. It protects them from bad eyes and stays them away from sins. There are many terms used for veiling like Hijab, Jilbab that are identical to the meaning of veil.Hijab is a test for the Muslim woman. It is clear from the Quran and the Hadiths that hijab is a religious obligation, which a woman has to undertake. There is no scholarly difference on this point and the Muslim Ummah has applied it for over 14 centuries. When a Muslim woman wears hijab, she is obeying and submitting to Allah. A woman who wears hijab liberates herself from the vain and selfish desire to show off her beauty and to compete with other women around her. In the Quran, the term hijab refers to a partition or curtain in the literal or metaphorical sense. The verse where it is used literally is commonly understood to refer to the curtain separating visitors to Muhammads(ï·º) house from his wives lodgings. This leads Muslim women that hijab is mandatory and to wear hijab is applied to every Muslim woman as many quranic verses denote on it. Muslim woman should cover her all body with curtain when she goes outside of the house as well as cover her face from unknown person whereas it is allowed to her to show her face, hands and legs to her relatives.In this article, the researcher conducted the research in the term of Islamic teachings of veiling and hijab for Muslim women in the light of Surah Ahzab and analyzed six verses of the concerned surah that described veiling. The researcher explained everything with some hadiths and some books and references. This article especially helps those women who are totally confused about face and body hijab as well as those who dont accept hijab as the sharia verdict of Allah and His prophet ï·º. This also helps those students who are newly doing research on hijab and veil. In fact, this article is very informative at all.

This paper explores the possibility of applying structuring injunctions in Brazilian civil procedural law. Utilizing literature review, this study explores whether the Brazilian, constitutional and infraconstitutional normative system is apt for the adoption of structuring injunctions without contradicting or affronting the current legal system. To this end, this article analyzes the constitutional principles of access to justice, the division of state functions, as well as the principles of demand and correlation. It also studies legislative innovations of the Brazilian Code of Civil Procedure of 2015, specifically the general procedural clauses and the principle of collaboration. This study then goes on to study article 21 of the Law of Introduction to Norms of Brazilian Law, which adopts explicitly the use of structural measures in the judicial decision-making process.

Abstract:
This study offers a critical analysis of the Dilalah Lafz ala al-Ahkam method (verbal indication of legal rulings) as conceptualized by Hasan al-Turabi, with particular emphasis on his interpretive approach to Qur’anic injunctions concerning prohibited forms of marriage. Employing a qualitative, library-based research methodology, this paper adopts a descriptive-analytical framework and draws primarily from al-Tafsir al-Tawhidi as the central textual source. The theoretical underpinning is grounded in the framework of mantuq and mafhum—a methodological apparatus developed by Khalid Ibn Uthman al-Sabt for legal hermeneutics within the Dilalah Lafz tradition. The analysis proceeds by identifying and cataloguing relevant Qur’anic verses addressing prohibited marriages, explicating al-Turabi’s hermeneutical approach, and subsequently assessing it through the lens of mantuq and mafhum theory. The findings suggest that al-Turabi’s interpretative method is consistent with the analytical strategies of the Mutakallimin school, especially in his reliance on explicit (mantuq) and implicit (mafhum) textual meanings to derive legal rulings.

Abstract:
An in-depth knowledge of the Objectives of Shariah, as intended by Allah the Lawgiver, is needed for analytical research when enacting Shariah. The question arises regarding the level of Arabic language knowledge required to understand Shariah before one is considered bound by Shariah injunctions. The main aim of this study is to elaborate on the classification of the Objectives of Shariah as advanced by al-Shatibi, especially, the objective of enacting Shariah for proper understanding (Ifhām). Also discussed in this study are the identification of foreign terms introduced into the Arabic language, if any found in the Quran, the knowledge of rules relating to customary usage of Quranic Arabic as understood by both laymen and experts, and the role these play in deducing the objectives of enacting Shariah. Another objective of Islamic law is the secondary connotation, whereby each interpreter understands the same text differently. This is the basis for translated text of Shariah. The findings of this study reveal that, firstly, there are no non-Arabic terms in Shariah text; second, Shariah text have both primary and secondary connotations which pose problems in translation; third, the Arabic language text was revealed to an unlettered Arab who understood it and implemented the demands of the text; fourth, there are linguistic maxims from which objectives result, as raised by al-Shatibi; finally, al-Shatibi re-defined in detail both primary and secondary connotations of Sharia texts due to their significance, since command and prohibition verses may independently convey such injunctions.

Full text
Abstract:
Exploring how notions of solitude in Pali literature are encompassed in various literary forms, such as stock formulae, poetry, narrative, and imagery, this book includes close analysis of some of the most famous Buddhist verses about solitary practice. Indaka Nishan Weerasekera considers how solitude is valued as one significant aspect of the Buddhist path, including how the imagery of landscape, especially the forest, serves to both inspire solitary practice as well as functions as a metaphor for meditation. The author employs a cross-section of primary sources to explore the practical and psychological aspects of solitude in relation to Buddhist meditation, as well as relational/attitudinal concepts such as renunciation or desirelessness, independence, and self-reliance. This ‘lonely’ aspect of the Buddhist path sits alongside the ‘communal’ aspect of the Buddhist teachings. Together, they serve to maintain monastic harmony, while the ‘social’ aspect preserves monastic relations with wider society.

Abstract:
Abstract The problem of divinely prescribed evil arises only if we have a moral interpretation of Scriptural injunctions, and can be resolved once we reject that interpretation in favor of a legal interpretation of Scriptural injunctions. Ibn Tufayl’s philosophical tale Hayy ibn Haqzān can help us understand the social function of religious laws and why it is rational to legislate nonoptimal moral rules under nonideal conditions. An argument for Legal Interpretation is offered in light of Ibn Tufayl’s idea and the planning conception of law. This argument reveals that there is a grain of truth in the contextualization view. The chapter also discusses the moral functions of Scripture in our modern world.

This chapter investigates the structure and expressive content of rock songs without choruses. Those that contain verses and bridges follow AABA form, and those that contain only verses follow strophic form. The chapter looks at the types of verses found in these forms (overwhelmingly sectional verses, especially following an srdc layout), as well as methods of creating large-scale coherence without a focal chorus section. Finally, the chapter looks at issues in AABA form, including B A fusion, where a single section functions as contrasting bridge and recapitulatory A, and chorus-like B sections, where the functional bridge suggests some elements of chorus function.

Full text
Abstract:
This chapter examines the significance of birds in Christopher Smart’s long religious poem, Jubilate Agno. Situating the many references to birds within the overall plan and layout of the poem’s complex pairing of “For” and “Let” verses, the chapter shows how Smart endows his birds with rhetorical agency. Examining the range of para-linguistic functions attributed to birdsong, the chapter links their effects to contemporary debates about elocutionary performance, notably in the work of Thomas Sheridan. Although Smart’s example of the “Mocking-bird” suggests the poem as a whole might be orchestrating a general mocking bird technology of imitation, the chapter argues that the poem demonstrates a different kind of technology, a technology of elocution, or rhetorical performance. The rhetorical agency of birds links this emphasis on elocution to the voice of all creatures.

Full text
Abstract:
The ancient Indian gāthā – a proverbial, succinct type of single-stanza poetry, often collected in thematic sets – became a favoured form of expression among groups of ascetics from the middle to the end of the 1st millennium BCE. This poetry – contrasting with the magico-ritual chant or mantra of the priest and the artistic poem of the aesthete – functions as (self-)instruction for the ascetic/renouncer. Examples include gāthās that exhort him to be as untiring as the Sun in its daily course, or to “wander alone like the rhinoceros!” This chapter delineates the figure of the solitary, wandering renouncer in a selection of Brahmanic, Jaina, and Buddhist ascetic gāthā-verses from that period. Particular attention is given to the use of solar and heroic imagery for describing the ideal renouncer, and how this relates to the real-life conditions of wandering renouncers.

Full text
Abstract:
Inscriptions appear on the walls throughout the Alhambra, including verses from the Qurʾān, formulaic phrases and poetry, yet there has been little effort to understand the epigraphy in relation to the architecture and the decorative programs. This chapter argues on both historical and theoretical grounds that the epigraphy in the Alhambra, and above all, the poetic inscriptions, served a vital role as a guide to the aesthetic experience of the Nasrid beholder. Discussion begins with an overview of the functions of the various epigraphic modes, especially the use of poetic inscriptions in the history of Islamic architecture and luxury objects within a comparative Mediterranean context. The analysis then draws on contemporary literary theory to explain one of the characteristic poetic tropes in the Alhambra, namely prosopopeia, the figure that creates the fiction that an otherwise inanimate object, such as a building, is speaking in the first person. The discussion focuses on the Sala de la Barca, in which the prosopopeia in the poetic inscriptions allows the architecture to address the beholders directly, arresting their movement in this threshold space, and leading them— in the terms of the optical theory examined in chapter one—from perception to cognition.

Full text
Abstract:
Abstract The objective of bit selection is to drill a round, ledge free hole, without patterns, with minimum vibration, minimum dog leg severity, that reaches all directional and geologic targets. And to do this in one run per section where rate of penetration (ROP) is unconstrained by the bit, and it remains vibration free in control drilling situations. The objective of this paper is to share these guidelines, accumulated from forensics investigations and sometimes costly lessons learned over the past decade. Bit selection can be based on; offset runs, forensics analysis, and first principles. Offsets capture past learnings. Forensics analysis is applied to past and current wells, and it is the foundation for continuous improvement. First principles, based on independent thinking, are required to challenge the status quo. These guidelines are the distillation of forensics observations, offset analysis, and physics modeling. It is important to note that these are guidelines, not rigid standards. They are presented in their current state, to be challenged, tested, and revised as new ideas and technology are developed. They are not a substitute for thinking. The guidelines start with a description of the formation properties, drilling environment, and other requirements such as directional objectives, drill out considerations, and required life. They cover how to suppress bit whirl, stick slip, and borehole patterns; improve structural integrity, allow for predictable build rates, reduce gauge trimmer damage, and design for appropriate aggressiveness, ribbon flow, bit stability and life. These functions and dysfunctions are paired with design features such as depth of cut elements; gauge pad length and relief; cutter materials, size, and geometry; back rake; blade count and standoff; hydraulic design; and blade strength. The guidelines document specific and general lessons learned and why each rule was established. They help drilling engineers and service companies determine which design features are most important for a given application. Applying them across teams and applications highlights design elements that may be of concern and has helped avoid repeat failures. The first failure is for learning, the second failure is a failure to learn. Design features have been matched up with associated critical performance limiters. This transparency in thinking allows the assumptions to be questioned, provides knowledge of which rules apply in each application, and provides background to evaluate when new technology may help. Some of the hard problems that remain are; consistent forensics analysis, chip flow modeling, cutter stress verses rock strength and penetration per revolution, understanding and suppressing high frequency torsional oscillation, and improvement and expansion of in-bit instrumentation.
