The Messenger of Allah ﷺ used to come to Umm Sulaym's house and sleep on her bed when she was not at home. She would arrive and find him asleep. Whenever he, peace and blessings be upon him, slept, his sweat would flow profusely. She would gather his sweat with a piece of cotton into a flask and add it to her perfume.
حدثنا محمد بن عبد الله حدثنا حميد
كان رسول الله ﷺ يأتي بيت أم سليم فينام على فراشها وليست أم سليم في بيتها فتأتي فتجده نائما وكان عليه الصلاة والسلام إذا نام ذف عرقا فتأخذ عرقه بقطنة في قارورة فتجعله في مسكها
