Abi Ja'far al-Nahhas's seminal work, 'Al-Nasikh wal-Mansukh fi al-Quran al-Karim,' is a cornerstone text in the study of Quranic sciences. It meticulously explores the intricate concept of abrogation (nasikh wal-mansukh) within the Holy Quran, a crucial discipline for understanding Islamic jurisprudence and scriptural interpretation. Al-Nahhas, a prominent 10th-century scholar, systematically identifies verses believed to have been superseded by others, examining their historical context, linguistic nuances, and legal implications. This book provides invaluable insights into the methodological approaches employed by early Islamic scholars to reconcile apparent textual contradictions, offering a comprehensive guide for both students and advanced researchers in Quranic studies. Its enduring relevance highlights the depth of classical Islamic scholarship on scriptural hermeneutics.
