2. Ali ibn Ibrahim has narrated from his father from Ibn Abi ‘Umayr from Hammad from Mansur ibn Hazim who has said the following: “Abu ‘Abd Allah , has said that

when Jibril (Gabriel) descended with Adhan to the Messenger of Allah, he was resting and his head was on Amir al-Mu’minin Ali’s lap. Jibril then read Adhan and Iqamah. When the Messenger of Allah woke up he asked, ‘O Ali, did you hear it?’ He replied, ‘Yes, I did.’ He (the Messenger of Allah) asked, ‘Do you remember it?’ He (Ali) replied, ‘Yes, I remember.’ He (the Messenger of Allah) then said, ‘Call Bilal and teach him.’ Ali then called Bilal and taught him Adhan and Iqamah.’”
