محمد بن جرير الطبري
Ibn al-Mughallis was a student of Muhammad ibn Jarir al-Tabari. Ibn al-Mughallis praised his teacher extensively, referring to him as possessing both the greatest understanding, and concern for scholarship of any theologian Ibn al-Mughallis had known. In particular, Ibn al-Mughallis considered Tabari's History of the Prophets and Kings to be one of the greatest books written at that point in history. Ibn al-Mughallis was also a student of Muhammad bin Dawud al-Zahiri, whose body he ritually washed as part of the Islamic funeral rite.
