صحيح مسلم

Anas b. Malik reported that Allah's Messenger (ﷺ) came to the house of Umm Sulaim and slept in her bed while she was away from her house. On the other day too he slept in her bed. She came and it was said to her: It is Allah's Messenger (ﷺ) who is having siesta in your house, lying in your bed. She came and found him sweating and his sweat falling on the leather cloth spread on her bed. She opened her scent-bag and began to fill the bottles with it. Allah's Messenger (ﷺ) was startled and woke up and said: Umm Sulaim, what are you doing? She said: Allah's Messenger, we seek blessings for our children through it. Thereupon he said: You have done something right.
