Hadith 603
´It was narrated that Umm Salamah said:` "I said, O Messenger of Allah! I am a woman with tight braids. Should I undo them when I take a bath to cleanse myself from the state of sexual impurity?" He said: "Rather it is sufficient for you to pour three handfuls of water over yourself, and you will be purified," or he said: "In that case you would have become purified."
Hadith 604
´It was narrated that 'Ubaid bin 'Umair said:` "Aishah heard that 'Abdullah bin 'Amr was telling his wives to undo their braids (when they bathed). She said: 'How odd that Ibn 'Amr would do that! Why does he not tell them to shave their heads? The Messenger of Allah and I used to bathe from a single vessel, and I never did more than pour three handfuls of water over my head.'"
