Ibn 'Abbas said:

I came to the Messenger of Allah (ﷺ) at the end of the night and prayed behind him. He took me by the hand and pulled me until I was standing beside him. When the Messenger of Allah (ﷺ) turned back to his prayer, I stepped back and the Messenger of Allah (ﷺ) continued praying. When he finished praying he said to me, "How come I put you beside me and you stepped back?" I said: O Messenger of Allah, is it appropriate for anyone to pray next to you when you are the Messenger of Allah to whom Allah has given...? He liked that and prayed to Allah to increase me in knowledge and understanding. Then I saw the Messenger of Allah (ﷺ) sleep until I heard him breathing deeply, then Bilal came to him and said: O Messenger of Allah, the prayer. And he got up and prayed and did not repeat wudoo’.
