Sayyiduna Ibn Abbas (may Allah be pleased with them both) narrates that once I stayed the night at the house of my maternal aunt, Umm al-Mu'mineen Sayyidah Maymunah bint al-Harith (may Allah be pleased with her). During the night, the Prophet (peace and blessings be upon him) stood up to pray, so I stood on his left side to join the prayer. The Prophet (peace and blessings be upon him) took me by the head and made me stand on his right side.
