Studi pemikiran Raden Haji Muhammad Nuh Cianjur tentang penentuan arah kiblat dalam kitab Risalah al-Qiblah
No full textPerkembangan ilmu pengetahuan dan teknologi pada saat ini memang sangat memungkinkan untuk menemukan arah kiblat yang lebih akurat. Risalah al-Qiblah karya Raden Haji Muhammad Nuh Cianjur merupakan kitab yang membahas mengenai penentuan arah kiblat yang dilengkapi data nilai arah kiblat terhadap Barat dan Utara untuk 18 Kota di Indonesia dan arah kiblat untuk 278 kota diseluruh dunia (Asia, Afrika, Eropa, dan Australia).
Melihat permasalahan di atas, penulis ingin menganalisis akurasi arah kiblat dalam kitab tersebut dengan teori dan perhitungan yang sama dan modern. Sehingga penulis merumuskan dua masalah dalam penelitian ini, yaitu bagaimana pemikiran Raden Haji Muhammad Nuh dalam penentuan arah kiblat? dan bagaimana tingkat akurasi arah kiblat dalam kitab Risalah al-Qiblah karya Radsen Haji Muhammad Nuh Cianjur?
Metode yang digunakan penulis dalam penelitian ini adalah metode kualitatif, dengan data primer yaitu Kitab Risalah al-Qiblah dan wawancara dengan peneliti sebelumnya. Sedangkan data skundernya penulis mengambil dari buku-buku dan karya ilmiah yang berhunungan dengan arah kiblat. mengenai analisis data penulis menggunakan metode deskiptif analitik yaitu analisis dengan menggambarkan perhitungan arah kiblat dengan teori yang ada.
Hasil penelitian menunjukkan bahwa setelah penulis melakukan observasi, ternyata ditemukan hasil arah kiblat dari kitab Risalah al-Qiblah selisih 2˚ dengan teori perhitungan segitiga bola. Artinya arah kiblat dalam kitab Risalah al-Qiblah bisa dikatakan akurat bila memakai teori segitiga bola karena masih dalam konteks Ihtiyatul Kakbah.
ABSTRACT:
The development of science and technology at this time is indeed very possible to find a more accurate Qibla direction. The Risale al-Qiblah by Raden Haji Muhammad Nuh Cianjur is a book that discusses the determination of the Qibla direction which is equipped with data on the Qibla direction values to the West and North for 18 Cities in Indonesia and the Qibla direction for 278 cities around the world (Asia, Africa, Europe and Australia ).
Seeing the problems above, the author wants to analyze the accuracy of the Qibla direction in the book with the same and modern theories and calculations. So the authors formulate two problems in this study, namely how Raden Haji Muhammad Nuh's thoughts in determining the Qibla direction? and what is the level of accuracy of Qibla direction in the book Risale al-Qiblah by Radsen Haji Muhammad Nuh Cianjur?
The method used by the author in this study is a qualitative method, with primary data, namely the Book of Risale al-Qiblah and interviews with previous researchers. While the secondary data the author takes from books and scientific works related to the Qibla direction. regarding data analysis the author uses descriptive analytic method, namely analysis by describing the calculation of Qibla direction with existing theory.
The results showed that after the writer made observations, it was found that the results of the Qibla direction from the Risale al-Qiblah book had a difference of 2˚ with the spherical triangle calculation theory. This means that the Qibla direction in the Risale al-Qiblah book can be said to be accurate when using the spherical triangle theory because it is still in the context of the Ihtiyatul Kaaba

PEMIKIRAN MUHAMMAD ASY-SYAIBANI TENTANG KASB DAN RELEVANSINYA DENGAN HUKUM EKONOMI SYARIAH
No full textThis research is motivated by the need to strengthen the framework of Islamic economic law, which is not only oriented towards material profit but also emphasizes justice, business ethics, and social responsibility amid the challenges of globalization and digitalization. The concept of kasb (work or effort) as initiated by Imam Muhammad asy-Syaibānī in his work Kitab al-Kasb is one of the fundamental references in classical Islamic economic thought. Asy-Syaibānī’s thought emphasizes that work is not merely an economic activity but also an act of worship and a means of achieving social justice. This research addresses the fundamental question of how asy-Syaibānī’s concept of kasb can be actualized within the framework of contemporary Islamic economic law.
This study uses a qualitative method with a library research approach. The primary source analyzed is Kitab al-Kasb by Muhammad asy-Syaibānī, using Friedrich Schleiermacher’s hermeneutics as the main theoretical approach. This approach allows an in-depth interpretation of classical texts by considering the historical, linguistic, and psychological context of the author. Thus, the values of kasb can be explored, understood, and applied in the context of modern Islamic economic law. Islamic economic law serves as the normative foundation to link the concept of kasb with contemporary issues in Islamic business law in the era of globalization and digitalization.
The results of this research show that asy-Syaibānī’s concept of kasb is highly relevant to the fundamental principles of Islamic economic law, especially in supporting the realization of the maqāṣid al-sharī‘ah, such as the protection of wealth (hifz al-māl), fair distribution, and business ethics. Through the hermeneutical approach, Islamic work values such as honesty, responsibility, and justice can be integrated into e-commerce practices, worker protection, and the strengthening of sharia business regulations that are adaptive to digital era challenges. This research is expected to contribute theoretically and practically to strengthening a fair, sustainable, and contextual Islamic economic legal framework

No full textThe ever-evolving science and technology provide new innovations for the development of money. This development gave birth to electronic money which was widely used by the public. One of the causes of polemic towards e-money is how the fiqh ulama approach fiqh to top up e-money. Fiqh approach is very important for contemporary problems to punish a problem and its derivatives. The purpose of this study is to analyze how contemporary ulama approach fiqh towards the e-money top up contract. There are at least four fiqh approaches to top up e-money, namely al-Ijarah al-Maushufah fi Dzimmah, Wadi'ah, Qard, and Sharf. The method used in this research is a qualitative method with the type of library research. From the research results, it is found that the more appropriate fiqh approach when a customer top up e-money is the sharf contract, namely the exchange of currency with electronic money. With this approach, the discount given by the publisher to the customer is not usury but a gift that is allowed by syara 'as a promotional step for e-money issued by the publisher.
The influence of al-Sahihayn on popular hadith literatures: the case of Khazinah al-AsrarJalilah al-Adhkar
No full textThe compilations of authentic hadith by al-Bukhari (d. 870) and Muslim (d. 875) known
collectively as al-Sahihayn serve for the Sunnis as the second highest source of religion after the
Quran. The stringent methods in hadith selection and appraisal in these books have contributed
to their credibility and reliability as a primary religious source, and many succeeding works
attempted to emulate them, though with varying results. Some popular hadith literatures have
also utilized al-Sahihayn as their main source of hadith quotation to enhance their status of
acceptance, notwithstanding some compromises and modifications. This is particularly the
case with a 19th century hadith compilation known as Khazinah al-Asrar Jalilah al-Adhkar by
Muhammad Haqqi al-Nazilli (d. 1884). Thus, this paper aims to delve into this topic in further
details. It attempts to analyze the role and influence of al-Sahihayn on Khazinah al-Asrar, the
extent of compliance of its author with the former, and the overall implication of its extensive
methodology on succeeding hadith works, particularly in Southeast Asia

AL-QUR’AN DAN ISLAMISASI BAHASA ARAB
No full textAl Qur’an was sent down to Prophet Muhammad SAW as the Holy book by Arabic. Allah decided Arabic as one of miracles because it was the pure language and uninfluenced by any concept, philoshopy of religion, and doctrines by other cultures; and also built by a great roof of words with eternally semantic guarded purity. In Jahiliyah, Arabic was stated as sastra language. It was changed as a science of language since itwas sent down as wahyu. By this case, author decided that process (the alteration from sastra to be wahyu) is a part of Islamization process. The terms, definitions, and new key words come from Islamization process. Those concepts gave new sense which was different in using and understanding before Al qur’an was sent down. Islamization Arabic, worldview, and framework of the society were changed into Islamic substance
