That he composed more than half of the exegesis in the life of his sheikh al-Mazzi (died 742 AH), based on the fact that he mentioned when interpreting Surat al-Anbiya his sheikh al-Mazzi and prayed for him for a long life. Abdullah Al-Zayla’i (died 762 AH) quoted him in his book Takhreej Ahadith al-Kashshaf, which indicates that it was spread before the year 762 AH. It is likely that he finished his exegesis on Friday, 10 Jumada al-Thani 759 AH, when it came in the Meccan version, which is considered the oldest copy.
