Abdullah bin Abbas reported,

I spent the night at the house of my aunt Maymunah. The Messenger of Allah ﷺ got up during the night, untied the waterskin and performed ablution, then refastened the waterskin and stood up to pray. I got up and performed ablution just as he had done, then came and stood on his left side. He took hold of me with his right hand and turned me around behind him, placing me on his right side, and I prayed with him.In another narration, he took hold of my head, or my forelock, and placed me on his right side.

Sahih

عن ابن عباس قال

بت في بيت خالتي ميمونة، فقام رسول الله ﷺ من الليل، فأطلق القربة فتوضأ، ثم أوكا القربة، ثم قام إلى الصلاة، فقمت فتوضأت كما توضأ، ثم جئت فقمت عن يساره، فأخذني بيمينه فأدارني من ورائه فأقامني عن يمينه، فصليت معه. وفي رواية: فأخذ برأسي، أو بذؤابتي فأقامني عن يمينه.
