ʻAbd al-Raḥīm ibn al-Ḥasan Isnawī

Jamāl al-Dīn Abū Muḥammad ʿAbd al-Raḥīm ibn al-Ḥasan al-Umawī al-Qurashī al-Isnawī al-Shāfiʿī al-Miṣrī , commonly known as Jamal al-Din al-Isnawi , was a Sunni Egyptian scholar who specialized in the Shafi'i school of jurisprudence, legal theory, Qu'ran exegesis, and Arabic grammar. He was a well-known, prolific writer who authored beneficial books.

Life He was born in 704 AH (1305 CE) in the city of Isnā in southern Egypt. From his father, he studied jurisprudence (fiqh), inheritance law (farāʾiḍ), and Arabic. During this time, he also memorized the Qur'an. In 721 AH (1321 CE), he went to Cairo and studied under prominent scholars. Al-Isnawi studied hadith and engaged in various sciences. He took jurisprudence from Taqi al-Din al-Subki, Jalal al-Din al-Qazwini, Qutb al-Din al-Sunbātī, al-Wajizi, and others. He studied grammar under Abu Hayyan al-Gharnati and read with him (al-Tashil), and he mastered the rational sciences from Alāʾ al-Dīn al-Qunawī and al-Tustari and others. He devoted himself to reading and benefiting others, and he engaged in writing and compiling works. He became one of the well-known scholars of his time in the fields of Arabic language and literature, jurisprudence, and its principles (uṣūl).

He had deep familiarity with the earliest sources of the Shāfiʿī school as well as later foundational texts and commentaries, particularly al-Rāfi'ī's al-Sharḥ al-Kabīr and al-Nawawī's Rawdat al-Talibin. Despite the fame of al-Nawawī and al-Rāfiʿī within the school, he criticized them and accused them of ignorance regarding Shāfiʿī opinions. For this purpose, he composed his work al-Muhimmāt. Some Shāfi'ī jurists also wrote refutations of Isnāwī, claiming that he did not properly understand al-Nawawī. “He advanced in jurisprudence and became the Imam of his time, and the leadership of the Shafi'i school ended with him.“
