‘A'isha said that a woman of the Ansar asked the Prophet about washing after menstruation and he instructed her how to do it, saying,
“Take a piece of cotton with musk and purify yourself with it.” She asked how she should do this, and he replied, “Purify yourself with it.”
She asked again how she should do this and he replied, “Praise be to God! Purify yourself with it.” ‘A'isha then drew her aside and said, “Go over the mark of the blood with it.”
Ibn ‘Abbas reported Maimuna as saying, "I set out water for the Prophet to wash and concealed him with a garment. He poured water on his hands and washed them, then poured water with his right hand over his left, then washed his private parts, then put his hand on the ground and wiped it. He then washed it, rinsed his mouth, snuffed up water, washed his face and forearms, then poured water over his head and emptied it out over his body, after which he moved aside and washed his feet. I handed him a garment, but he did not take it; he went off shaking his hands."
(Bukhari and Muslim, the wording being Bukhari’s.)
Umm Salama said she told God’s messenger that she kept her hair closely plaited, and asked whether she should undo it when washing after sexual defilement. He replied, “No, it is enough for you to throw three handfuls over your head, then pour water over yourself, and you will be purified.”
‘A'isha said that when God’s messenger washed because of a seminal emission he first washed his hands, then performed ablution as he did for prayer, then put his fingers into the water and moved them through the roots of his hair, then poured three handfuls on his head with both hands, then poured the water over all his skin.
(Bukhari and Muslim.) In a version by Muslim he first washed his hands before putting them into the vessel, then poured water over his left hand with his right hand, then washed his private parts, after which he performed ablution.
