Narrated Woman of Banu Ghifar: Umayyah, daughter of AbusSalt, quoted a certain woman of Banu Ghifar, whose name was mentioned to me, as saying: The Messenger of Allah ﷺ made me ride behind him on the rear of the camel saddle. By Allah, the Messenger of Allah ﷺ got down in the morning. He made his camel kneel down and I came down from the back of his saddle. There was a mark of blood on it (saddle) and that was the first menstruation that I had. I stuck to the camel and felt ashamed. When the Messenger of Allah ﷺ saw what had happened to me and saw the blood, he said: Perhaps you are menstruating. I said: Yes. He then said: Set yourself right (i. e. tie some cloth to prevent bleeding), then take a vessel of water and put some salt in it, and then wash the blood from the back of the saddle, and then return to your mount. When the Messenger of Allah ﷺ conquered Khaybar, he gave us a portion of the booty. Whenever the woman became purified from her menses, she would put salt in water. And when she died, she left a will to put salt in the water for washing her (after death).

Ibn Abbas said: The Prophet ﷺ lifted the curtain (and saw that) the people were standing in rows (of prayers) behind Abu Bakr. He said: O people, there remained nothing that gives good tidings from prophethood except a true dream which a Muslim has himself or which another Muslim has for him. I have been prohibited to recite the Quran while bowing or prostration. As regards owing, exalt the Lord in it, and as to prostration, make supplication with exertion in it, that is worthy of being accepted.
