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 (ﷺ) 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 (ﷺ) collectedhair on their heads and these lopped up to ears (and did rot go beyond that)
