It was narrated that Ibn 'Abbas (رضي الله عنه) said:

I stayed overnight in the house of my maternal aunt Maimoonah. The Messenger of Allah (ﷺ) prayed Isha', then he came and prayed four (rak’ahs). Then he said: “Has the little boy gone to sleep?" - Shu'bah said: or something like that. - Then he went to sleep; then he got up and did wudoo. I do not remember how he did wudoo. Then he got up and prayed, and I stood on his left, but he made me stand on his right. Then he prayed five rak’ahs, then he prayed two. Then he went to sleep until I heard him breathing deeply, Then he prayed two rak’ahs, then he went out for the prayer.
