Muḥammad Ibn al Fadl said: I heard my grandfather say: I asked my father for permission to study under Qutaybah, so he said: First learn the Qurʾān and then I will give you permission. So I memorized the Qurʾān by heart. So he said to me: Remain until you have led the people in prayer (tarāwīh) with it. So I did so, then after the ʿĪd he gave me permission, so I left for Marw.
