Zuhayr ibn Harb narrated to me: Hashim — meaning Ibn al-Qasim — narrated to us, from Sulayman, from Thabit, from Anas ibn Malik, who said: The Prophet, peace and blessings be upon him, entered upon us and stayed with us, and he sweated. My mother came with a bottle and began collecting the sweat into it. The Prophet, peace and blessings be upon him, woke up and said, "O Umm Sulaym, what is this that you are doing?" She said, "This is your sweat; we put it in our perfume, and it is among the most fragrant of perfumes."
