It was narrated from Ibn 'Abbas (رضي الله عنه) that he came to his maternal aunt Maimoonah, the wife of the Prophet (ﷺ). He said:

The Messenger of Allah (ﷺ) got up at night, and went to a waterskin and did wudoo’, then he stood and prayed. Then I got up and did wudoo’, and I stood to his left. He took me by the hand and pulled me behind him, until he made me stand on his right.
