Abstract

This research aims to investigate access to justice for children and women in the Religious Court Decisions after the issuance of Circular Letter of Supreme Court No. 4 of 2016, Point 5 on Religious Chamber. This particular point states that the Religious Court can require a father to provide child maintenance if the child is under the custody of the mother. This is a normative study, with the data obtained from interviews and 150 Religious court decisions. These decisions are issued by the Religious Courts of East Jakarta and Central Jakarta from 2015-2017. The examination of those Decisions reveals that most of the decisions on divorce do not mention any stipulation about child maintenance. This means that the Supreme Court Circular No. 4 of 2016 has not been able to protect children rights in the case of divorce, as well as women’s rights. From the court used in this study, only 14% that require the fathers to provide child maintenance after divorce. This percentage is almost similar to the decisions issued before the issuance of the Circular, which only 12% in 2016, and 14% in 2017.     AbstrakPenelitian ini bertujuan untuk mengetahui akses keadilan bagi anak dan perempuan dalam Putusan Pengadilan Agama pasca terbitnya Keputusan Mahkamah Agung Nomor 4 Tahun 2016 Poin 5 tentang Kamar Beragama. Dalam poin khusus ini disebutkan bahwa Pengadilan Agama dapat meminta seorang ayah untuk mengasuh anak jika anak tersebut berada di bawah asuhan ibunya. Penelitian ini bersifat normatif, dengan data diperoleh dari wawancara dan 150 putusan Pengadilan Agama. Putusan-putusan tersebut dikeluarkan oleh Pengadilan Agama Jakarta Timur dan Jakarta Pusat dari tahun 2015- 2017. Berdasarkan pemeriksaan terhadap Putusan tersebut, sebagian besar Putusan perceraian tidak menyebutkan ketentuan tentang pengasuhan anak. Artinya, Surat Edaran Mahkamah Agung Nomor 4 Tahun 2016 belum mampu melindungi hak anak dan hal perempuan dalam kasus perceraian. Data pengadilan yang digunakan dalam penelitian ini, menyebutkan hanya 14% yang mewajibkan ayah untuk mengasuh anak setelah perceraian. Persentase ini hampir sama dengan keputusan yang dikeluarkan sebelum keluarnya keputusan tersebut, yaitu hanya 12% pada 2016, dan 14% pada 2017.

Abstract

In the Islamic legal context, hibah has both worship and economic aspects. However, its practice often leads to problems when one or more terms determined by Islamic teachings are ignored. Among the violations in grant practice is granting hibah from property not fully owned by grantor. This paper aims to examine issues in resolving disputes on hibah (property granting) involving a shared property owned by a husband and wife. This study focuses on the examination of two judicial verdicts issued by the Religious Court (Verdict No.354 /Pdt.G/2022/PA.Pt) and the Appellate Religious Court (Verdict No. 222/Pdt.G/2022/PTA. SMG) on hibah dispute where hibah property contains shared property. This study finds that there are two approaches used by the judges in dealing with the issue. First, in the first instance court considered hibah void and revoked hibah. Similarly, the appellate court annulled hibah transaction but considered some part of the property to be rightful for grant. This is because hibah is taken from the property owned by grantor, which has been separated by his wife's property.

Abstract

This research attempts to look at the allocation of inheritance in polygamous marriages, as adjudicated by the Indonesian Islamic courts, commonly known as the Religious Courts. In a polygamous marriage, the inheritance distribution often faces more complex challenges. This research is grounded in an analysis of decisions from the Religious Courts, including both first-instance and appellate court rulings. The findings indicate that inheritance distribution in polygamous marriages relies not just on the Islamic Law Compilation, but also on the Indonesian Civil Code. Moreover, the judges employed two approaches to resolve disputes: Islamic jurisprudence (fiqh) and the Islamic Law Compilation, which is the codified Islamic law in Indonesia. When the judges referred to the classical texts of Islamic jurisprudence, they allocated the entirety of the inherited properties among the heirs. Negotiation occurred when judges opted for the Islamic Law Compilation instead of classical fiqh, leading them to consider the concept of joint property and distinguish it from the estates. Ultimately, the Appellate Court judges appeared more progressive, taking into account the Indonesian context and ensuring justice for wives in polygamous marriages.

Abstract

The vernacularity of the poetic translation of the Qur'an Nadoman Nurul Hikmah by Hidayat Suryalaga lies in its peculiarity in using the language and rules of Sundanese poetry of praise. This paper aims to explain the form of vernacularity in the translation of Nadoman Nurul Hikmah's interpretation by H. R. Hidayat Suryalaga. This article uses descriptive methods and content analysis, thus concluding that the aspect of nadoman content or the meaning of the verses in Nadoman Nurul Hikmah is far more accurately called a translation of tafsiriyah al-Qur'an than it is called poetic interpretation of the Qur'an. H. R. Hidayat Suryalaga, in Nadoman Nurul Hikmah, does not at all refer to the Arabic translation or interpretation in each stanza. H. R. Hidayat Suryalaga did not use the verse editor as a source, but he tried to provide his interpretation. Meanwhile, in Nadoman, Nurul Hikmah does the loose and contextual translation. The contextualization of the verses of the Qur'an gives the impression to the readers (singers) of Nadoman that Nadoman Nurul Hikmah can be enjoyed by anyone who is by the spirit of the times.

Abstract

This writing reexamines the position of humans in contemporary life. Humans, from ancient times until now, remain a significant enigma and a profound mystery. They are earthly beings, yet distinct from other earthly creatures in various aspects. They possess sacred values, yet cannot be equated with creatures that have been sanctified. This is because humans are a combination of both, filled with various potentials. The language of the Qur'an refers to them as 'Ahsan Taqwim' – the best of creation.

Abstract

Studies in various Muslim countries show that the fulfillment of child maintenance after divorce by fathers remains an issue. This paper examines the fulfillment of nafkah madiyah, or arrear maintenance for children, by the Religious Courts in Indonesia, especially after the issuance of Supreme Court Circular No. 2 of 2019. Relying on the analysis of ten Religious Court Decisions, this study finds that there have been inconsistencies in the Court Decisions in fulfilling the demand for nafkah madiyah submitted by mothers. The differences in the outcomes are caused by the different legal bases used by the judges and their consideration of men’s ability to fulfill the demands. The main reason for nafkah madiyah rejection is the judges’ arguments that maintenance costs are for children to take benefits from them (li al intifa’) and not for possession (li al tamlik). This means that if a father did not provide for his children in the past, his negligence does not become a debt to be paid in the future. Meanwhile, judges grant the request of nafkah madiyah because child maintenance is the father’s obligation. As in many cases, women are the primary carers of children after a divorce; ultimately, fulfilling nafkah madiyah is to protect not only children’s rights but also women’s rights. [Kajian terdahulu di beberapa negara Muslim menunjukkan bahwa pemenuhan nafkah anak oleh ayah masih menjadi masalah. Penelitian ini mengkaji pemenuhan nafkah terhutang (madiyah) untuk anak, oleh Pengadilan Agama di Indonesia, khususnya setelah lahirnya Surat Edaran Mahkamah Agung No. 2 Tahun 2019. Dengan analisis terhadap sepuluh Putusan Pengadilan Agama, studi ini menemukan bahwa terdapat inkonsistensi Putusan Pengadilan dalam memenuhi tuntutan nafkah madiyah yang dituntut oleh ibu. Perbedaan putusan tersebut disebabkan oleh perbedaan dasar hukum yang digunakan oleh para hakim dan pertimbangan mereka terhadap kemampuan laki-laki untuk memenuhi tuntutan tersebut. Alasan utama penolakan nafkah madiyah adalah argumen hakim bahwa biaya nafkah adalah untuk diambil manfaatnya oleh anak (li al intifa') dan bukan untuk dimiliki (li al tamlik). Artinya, jika seorang ayah tidak menafkahi anaknya di masa lalu, kelalaiannya itu tidak menjadi utang yang harus dibayar di masa depan. Sementara itu, hakim mengabulkan permohonan nafkah madiyah karena menganggap nafkah anak adalah kewajiban ayah. Sebagaimana dalam banyak kasus, perempuan adalah pengasuh utama anak setelah perceraian, pada akhirnya, pemenuhan nafkah madiyah adalah untuk melindungi tidak hanya hak anak tetapi juga hak-hak perempuan.]

Abstract

This research responds to the growing movement among certain Islamic mass organizations (Ormas) in Indonesia that continue to challenge the legitimacy of Pancasila as the state ideology by using the framework of civilization jurisprudence (fikih peradaban). These groups argue that Pancasila does not sufficiently accommodate Islamic law (syariah), which they claim should be prioritized as the legal foundation for a Muslim-majority nation. To critically examine these claims, this study employs content analysis to uncover the logical fallacies embedded within the ideological narratives produced by these Ormas. Primary data consist of written and digital narratives from organizations such as Hizbut Tahrir Indonesia (HTI), the Islamic Defenders Front (FPI), Jama'ah Ansharut Daulah (JAD), and Jama'ah Islamiyah—groups known to have transnational ideological affiliations, including links to ISIS. These narratives are sourced from official websites, organizational documents (such as constitutions and bylaws), and social media postings. Secondary data include reports from the Ministry of Home Affairs and the Ministry of Religious Affairs, as well as authoritative Islamic scholarly sources such as classical fiqh, usul fiqh, tafsir ahkam, academic journals, and credible news articles. The analysis reveals that the discourse promoted by these transnational Islamic groups frames Pancasila and the Quran as mutually exclusive, leading to an erroneous ideological dichotomy. Their reasoning is shown to be fallacious due to inappropriate comparisons, overgeneralizations, and the failure to understand the distinct epistemic categories between divine revelation and a contextual national ideology. The study concludes that fikih peradaban offers a constructive paradigm for harmonizing religious and national commitments, affirming that Indonesian law is inherently dynamic, contextual, and capable of integrating universal Islamic values without undermining Pancasila.
