It was narrated that 'Ubaid bin 'Umair said: "'Aishah heard that 'Abdullah bin 'Amr was telling the women to undo their braids when they performed Ghusl. She said: 'How strange it is, that Ibn 'Amr should tell the women to undo their braids when they perform Ghusl! Why doesn't he tell them to shave their heads? The Messenger of Allah (s.a.w) and I used to perform Ghusl from a single vessel, and I did not do more than pour water over my head three times (without undoing my braids)."'
