Sunan an-Nasa'i 1135

Muhammad ibn Rafi‘ reported to us; he said: ‘Abdullah ibn Ibrahim ibn ‘Umar ibn Kaysan narrated to us; he said: My father narrated to me, from Wahb ibn Manus, who said: I heard Sa‘id ibn Jubayr say: I heard Anas ibn Malik say: I have never seen anyone whose prayer more closely resembled the prayer of the Messenger of Allah (ﷺ) than this young man—meaning ‘Umar ibn ‘Abd al-‘Aziz. We estimated that he said the glorifications ten times in his bowing and ten times in his prostration.
