According to the Egyptian chronicler al-Kindi, Muzaffar was the first governor of Egypt to recite the takbir during the Friday prayers.[3] His activities regarding the mihnah, then underway in the provinces of the caliphate, are subject to debate; Ibn Taghribirdi reported that he tested the 'ulama' on the createdness of the Qur'an,[4] but this may be a doublet of events that occurred during his father's governorship.[5]
