It is narrated from Sayyiduna Ibn Abbas (may Allah be pleased with them both) that once I stayed the night at the house of my maternal aunt, Umm al-Mu'mineen Sayyidah Maymunah bint Harith (may Allah be pleased with her). During the night, the Prophet (peace and blessings be upon him) stood up to pray and performed ablution, so I also performed ablution to join the prayer and stood on his left side. The Prophet (peace and blessings be upon him) turned me around and placed me on his right side.
