Jumay' bin Umayr, 'the brother of Banu Taym Allah bin Tha'labah', said: I went with my mother and my maternal aunt to Sayyidah Aishah (may Allah be pleased with her). One of the two asked Sayyidah Aishah (may Allah be pleased with her): How did you do it at the time of the ritual bath? Sayyidah Aishah (may Allah be pleased with her) said: The Messenger of Allah (peace and blessings be upon him) would perform ablution like the ablution for prayer, then pour water over his head three times, and we would pour water over our heads five times because of our braids.
