Sayyiduna Ibn Abbas (may Allah be pleased with them both) narrates that I (one night) slept at the house of my maternal aunt Maymunah. When a portion of the night had passed, the Messenger of Allah (peace and blessings be upon him) got up and started to pray. Then he narrated some hadith and said: "Then I also got up and stood on his left side, so the Messenger of Allah (peace and blessings be upon him) turned me and made me stand on his right side."
