It is narrated from Wahb bin Manus that I heard Sa'id bin Jubayr say: Sayyiduna Anas bin Malik (may Allah be pleased with him) says that after the Messenger of Allah (peace and blessings be upon him) I have not prayed behind anyone whose prayer resembled his (peace and blessings be upon him) prayer more than this young man, by whom he meant Umar bin Abd al-Aziz (may Allah have mercy on him).
He says: We estimated his bowing and his prostrations to be (as long as the time it takes) to recite ten glorifications each.
Imam Abu Dawud (may Allah have mercy on him) says that Ahmad bin Salih (a narrator of the chain) says: I asked him whether the name is Manus or Mabus? He said: Abd al-Razzaq says Mabus, but in my memory it is Manus.
