Abū ‘Abd Allāh Muḥammad ibn Shihāb ad-Dīn Jalāl ad-Dīn al-Maḥallī (Arabic: جلال الدين أبو عبد الله محمد بن شهاب الدين أحمد بن كمال الدين محمد بن إبراهيم بن أحمد بن هاشم العباسي الأنصاري المحلّي; c. 1389–1460 CE); aka Jalaluddin was an Egyptian renowned mufassir and a leading specialist in the principles of the law in Shafi'i jurisprudence.
[1] He authored numerous and lengthy works on various branches of Islamic Studies, among which the most important two are Tafsir al-Jalalayn[2] and Kanz al-Raghibin, an explanation of Al-Nawawi's Minhaj al-Talibin, a classical manual on Islamic Law according to Shafi'i fiqh.
The mission of preparing the Tafsir was initiated by Jalal ad-Din al-Maḥalli in 1459 and completed after his death by his pupil Jalal ad-Din as-Suyuti in 1505, thus its name, which means "Tafsir of the two Jalals".
It is recognised as one of the most popular exegeses of the Qur'an today,[4] due to its simple style[4] and its conciseness, as it is only one volume in length.
The work has been translated into many languages including English, French, Bengali, Urdu, Persian, Malay/Indonesian,[5] Turkish, and Japanese.
