Sahih Muslim 2331 a
Anas b. Malik reported that Allah's Apostle (ﷺ) 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 (ﷺ) got up he said:
Umm Sulaim, 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.
حَدَّثَنِي زُهَيْرُ بْنُ حَرْبٍ، حَدَّثَنَا هَاشِمٌ، - يَعْنِي ابْنَ الْقَاسِمِ - عَنْ سُلَيْمَانَ، عَنْ 
 ثَابِتٍ، عَنْ أَنَسِ بْنِ مَالِكٍ، قَالَ دَخَلَ عَلَيْنَا النَّبِيُّ صلى الله عليه وسلم فَقَالَ عِنْدَنَا فَعَرِقَ
 وَجَاءَتْ أُمِّي بِقَارُورَةٍ فَجَعَلَتْ تَسْلُتُ الْعَرَقَ فِيهَا فَاسْتَيْقَظَ النَّبِيُّ صلى الله عليه وسلم
 فَقَالَ ‏
"‏ يَا أُمَّ سُلَيْمٍ مَا هَذَا الَّذِي تَصْنَعِينَ ‏"‏ ‏.‏ قَالَتْ هَذَا عَرَقُكَ نَجْعَلُهُ فِي طِيبِنَا وَهُوَ
 مِنْ أَطْيَبِ الطِّيبِ ‏.‏
