al-Isnawi (704–772 AH / 1304–1370 CE) was an Egyptian Shafi'i jurist, legal theorist, and grammarian who served as the leading Shafi'i authority in Cairo, best known for his legal commentary al-Muhimmat fi Sharh al-Rawda wa al-Rafi'i .

Lineage and Early Life

Abu Muhammad Jamal al-Din Abd al-Rahim ibn al-Hasan ibn Ali ibn Umar ibn Ali ibn Ibrahim al-Qurashi al-Umawi al-Isnawi was born in Esna in Upper Egypt in 704 AH / 1304 CE; reports place his birth in the final ten days of Dhu al-Hijja, while another account gives Rajab, and Ibn Rafi' recorded 703 AH . He was named after his paternal uncle, Jamal al-Din Abd al-Rahim ibn Ali, who died shortly before his birth . He memorized the Quran in Esna and reportedly committed Abu Ishaq al-Shirazi's legal manual al-Tanbih to memory in six months . Following his father's death in 718 AH, he remained in Esna for a time before moving to Cairo in 721 AH, where he took up residence at Dar al-Hadith al-Kamiliyya .

Education and Teachers

In Cairo, al-Isnawi studied jurisprudence under Qutb al-Din al-Sinbati, Jalal al-Din al-Qazwini, Majd al-Din al-Zankaluni, Taqi al-Din al-Subki, and Jamal al-Din al-Wajizi . He acquired legal theory and rational sciences from Ala al-Din al-Qunawi and Badr al-Din al-Tustari . He studied Arabic grammar with Abu al-Hasan Ali ibn Ahmad al-Ansari and Abu Hayyan al-Andalusi, under whom he read Ibn Malik's Tashil al-fawa'id; Abu Hayyan praised his precocity, noting that he had not conferred scholarly status on anyone of al-Isnawi's age before him . He also heard hadith from teachers including Yunus ibn Ibrahim al-Asqalani, Husayn ibn Asad ibn al-Athir, and Abd al-Muhsin al-Sabuni .

Teaching Career and Public Offices

Al-Isnawi commenced teaching and issuing legal opinions in 727 AH . He was appointed to teach jurisprudence at several Cairene colleges, including the Malikiyya, Aqbughawiyya, Farisiyya, and Fadiliyya madrasas, and taught Quranic exegesis at the Ibn Tulun Mosque . In public administration, he was placed in charge of the agency of the public treasury (wakalat bayt al-mal) and the market inspectorate (al-hisba) . In 762 AH, he resigned from the hisba following a dispute with the vizier Ibn Qazina, and subsequently relinquished his post at the treasury agency to dedicate his time fully to instruction and authorship .

Numerous scholars studied under him, including Siraj al-Din Ibn al-Mulaqqin, Badr al-Din al-Zarkashi, Zayn al-Din al-Iraqi, his son Abu Zur'a al-Iraqi, and Nur al-Din al-Haythami .

Scholarly Standing

Al-Isnawi attained preeminence among the Shafi'i scholars of Egypt, becoming widely recognized as the head of the school (shaykh al-Shafi'iyya) and its foremost mufti in his era . Ibn al-Mulaqqin characterized him as the leading teacher, mufti, and author of the Shafi'is of his time across jurisprudence, legal theory, and Arabic grammar . Biographers noted his pedagogical patience and generosity, observing that he paid special attention to struggling students and listened attentively to beginner queries .

In legal theory, his systematic commentary Nihayat al-Sul Sharh Minhaj al-Wusul established itself as one of the most widely consulted expositions of Nasir al-Din al-Baydawi's primer, while his treatise al-Tamhid fi Takhrij al-Furu alaa al-Usul examined the derivation of substantive legal rulings from foundational theoretical maxims .

Death

Al-Isnawi died suddenly in Cairo on the night of Sunday, 18 Jumada al-Ula 772 AH / December 1370 CE, though another account names 18 Jumada al-Akhira and a variant report gives 28 Jumada al-Ula . His funeral was heavily attended; Chief Judge Baha al-Din Abu al-Baqa led the prayer over him at the al-Hakim Mosque, and he was buried the following day in his mausoleum outside Bab al-Nasr near the Sufi cemeteries .
