Sayyiduna Ibn Abbas (may Allah be pleased with them both) narrates that once I spent the night at the house of my maternal aunt, Umm al-Mu'mineen Sayyidah Maymunah bint Harith (may Allah be pleased with her). The Prophet (peace and blessings of Allah be upon him) woke up during the night, opened the water-skin, performed ablution from it, and stood up to pray. So I stood on his left side to join the prayer, but the Prophet (peace and blessings of Allah be upon him) took me by my right hand and made me stand on his right side, and I performed the prayer with him.
