Sahih Muslim | Book 30 | Hadith Number 5761

Narrated by Anas b. Malik
Anas b. Malik reported that Allah's Apostle (may peace be upon him) used to come to our house and there was perspiration upon his body. My mother brought a bottle and began to pour the sweat in that. When Allah's Apostle (may peace be upon him) got up he said: Umm Sulaini, what is this that you are doing? Thereupon she said: That is your sweat which we mix in our perfume and it becomes the most fragrant perfume.
