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

I stayed overnight with my maternal aunt Maimoonah. The Prophet (ﷺ) got up to offer voluntary prayers at night. The Prophet (ﷺ) went to the waterskin and did wudoo’, then he stood and prayed. I got up when I saw him do that, and I did wudoo' from the waterskin, then I stood on his left. He took me by the hand from behind his back and took me like this from behind to his right side.
