Umm Hani bint Abi Talib · The Book of Purification

"A vessel was brought to Mujahid, which I estimated to be eight Ratls, and he said: 'Aishah told me that the Messenger of Allah (ﷺ) used to perform Ghusl using such a vessel.'"

"I said: 'O Messenger of Allah, I am a woman with tightly braided hair; should I undo it when performing Ghusl from Janabah?' He said: 'No it is sufficient for you to pour three handfuls of water over your body.'"
