Narrated Anas ibn Malik:
I did not offer behind anyone after the Messenger of Allah (ﷺ) a prayer like the prayer offered by the Messenger of Allah (ﷺ) than this youth, i.e. Umar ibn AbdulAziz. We estimated reciting glorification ten times in his bowing, and in his prostration ten times.
Abu Dawud said: Ahmad b. Salih said: I asked him ('Abd Allah) whether the name Manus is correct of Mabus. He replied: 'Abd al-Razzaq used to say Mabus, but I remember Manus (i.e. the narrator Wahb b. Manus). These are the words of Ibn Rafi'. It has also been narrated by Ahmad from Sa'id b. Jubair on the authority of Anas b. Malik.
