Sunan Abi Dawud Book 2, Hadith 220

when I was spending a night in the house of my maternal aunt Maimunah, the Messenger of Allah (ﷺ) got up at night, opened the mouth of the water skin and performed ablution. He then closed the mouth of the water-skin and stood for prayer. Then I got up and performed ablution as he did ; then I came and stood on his left side. He took my hand, turned me round behind his back and set me on his right side; and I prayed along with him.
