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.
Abu Salamab. 'Abd al-Rahman reported:
I along with the foster brother of 'A'isha went to her and he asked about the bath of the Apostle (s.a.w.a.) because of sexual intercourse. She called for a vessel equal to a Sa' and she took a bath. and there was a curtain between us and her. She poured water on her head thrice and he (Abu Salama) said: The wives of the Apostle (s.a.w.a.) collectedhair on their heads and these lopped up to ears (and did rot go beyond that).
It was narrated from Abu Bakr bin Hafs:
"I heard Abu Salamah say: 'I entered upon 'Aishah and her foster-brother was with her. He asked her about the Ghusl of the Prophet (s.a.w.a.). She called for a vessel in which was a Sa' of water, then she concealed herself and performed Ghusl and poured water over her head three times.'"
