Mansur ibn Abi Muzahim narrated to us, saying: Abdullah ibn al-Mubarak narrated to us, on the authority of Abu Bakr ibn Uthman ibn Sahl ibn Hunayf, who said: I heard Abu Umamah ibn Sahl say: We prayed the noon prayer (zuhr) with Umar ibn Abd al-Aziz, then we went out until we entered upon Anas ibn Malik, and we found him praying the afternoon prayer (asr). I said: O uncle, what is this prayer that you have prayed? He said: It is the afternoon prayer (asr), and this is the prayer of the Messenger of Allah, may Allah exalt him and grant him peace, which we used to pray with him.
