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

I stayed overnight in the house of my maternal aunt Maimoonah. The Messenger of Allah (ﷺ) got up at night, undid a waterskin and did wudoo’, then he stood and prayed. I stood on his left and he took hold of my hand and brought me around and made me stand on his right, and I prayed with him.
