Sayyiduna Ibn Abbas (may Allah be pleased with them both) narrates: I stayed the night with my maternal aunt Maymunah (may Allah be pleased with her). the Messenger of Allah (peace and blessings be upon him) slept, then woke up, performed ablution and used the miswak, and he kept doing so several times throughout the night.
