Al-Sabouni is influential because of his easy-to-read, simplified commentaries of the Holy Qur’an. They are now thought of as some of the most popular short commentaries in history after those of Jalalayn, Baydawi, Ibn Kathir and Ibn Juzayy. One of al-Sabouni’s most influential commentaries is the Tafsir Ayat Al-Ahkam, an exploration of the Qur’anic verses that pertain to legal rulings. The Institute of Scientific Research and Revival of Islamic Heritage at the Umm Al- Qura University in Makkah, Saudi Arabia commissioned al-Sabouni to investigate the ancient tafsir manuscript of Abu Jaafar al- Nahas (d. 949 CE/338AH). Al-Sabouni’s landmark achievement of verifying the only surviving manuscript of the text has come to fruition as a six volume work published by the university.
