Narrated to me Abu Kurayb, Muhammad ibn al-'Ala' al-Hamdani: narrated to us Khalid — meaning Ibn Makhlad — from Muhammad ibn Ja'far: narrated to us Hisham, from his father, from 'A'ishah, who said: Ibn Umm Maktum used to give the call to prayer (adhan) for the Messenger of Allah ﷺ, and he was blind.
