Narrated Abu Salama
`Aisha's brother and I went to `Aisha and he asked her about the bath of the Prophet. She brought a pot containing about a Sa` of water and took a bath and poured it over her head and at that time there was a screen between her and us.
Narrated Abu Ja`far
While I and my father were with Jabir bin `Abdullah, some people asked him about taking a bath. He replied, "A Sa` of water is sufficient for you." A man said, "A Sa` is not sufficient for me." Jabir said, "A Sa` was sufficient for one who had more hair than you and was better than you (meaning the Prophet)." And then Jabir (put on) his garment and led the prayer.
Narrated Ibn `Abbas
The Prophet (ﷺ) and Maimuna used to take a bath from a single pot.
