Sahih Muslim , Hadith 2332 ⓘ

Umm Sulaim reported that Allah's Apostle visited her house and (took rest) and she spread a piece of cloth for him and he had had a siesta on it. And he sweated profusely and she collected his sweat and put it in a perfume and in bottles. Allah's Apostle said: Umm Sulaim, what is this? She said: It is your sweat, which I put in my perfume. Allah's Apostle sweated in cold weather when revelation descended upon him.

حَدَّثَنَا أَبُو بَكْرِ بْنُ أَبِي شَيْبَةَ، حَدَّثَنَا عَفَّانُ بْنُ مُسْلِمٍ، حَدَّثَنَا وُهَيْبٌ، حَدَّثَنَا أَيُّوبُ، عَنْ أَبِي قِلاَبَةَ، عَنْ أَنَسٍ، عَنْ أُمِّ سُلَيْمٍ، أَنَّ النَّبِيَّ صلى الله عليه وسلم كَانَ يَأْتِيهَا فَيَقِيلُ عِنْدَهَا فَتَبْسُطُ لَهُ نَطْعًا فَيَقِيلُ عَلَيْهِ وَكَانَ كَثِيرَ الْعَرَقِ فَكَانَتْ تَجْمَعُ عَرَقَهُ فَتَجْعَلُهُ فِي الطِّيبِ وَالْقَوَارِيرِ فَقَالَ النَّبِيُّ صلى الله عليه وسلم ‏ "‏ يَا أُمَّ سُلَيْمٍ مَا هَذَا ‏" ‏ ‏.‏ قَالَتْ عَرَقُكَ أَدُوفُ بِهِ طِيبِي ‏.‏
