سنن أبي داود

'Aishah reported: Asma' entered upon the Messenger of Allah (ﷺ) and said: Messenger of Allah, how should one of us take bath when she is purified from her menses ? He said: She should take water mixed with the leaves of lote-tree; then should perform ablution and wash her head and rub it so much so that water reaches the roots of the hair; she should then our water upon her body. Then she should take a piece of cloth (or cotton or wool) and purify with it. She asked: Messenger of Allah, how should I purify with it ? 'Aishah said: I understood what he (the Prophet) said metaphorically. I, therefore, said to her: Remove the marks of blood.
