[Machine] The Prophet ﷺ used to enter the house of Umm Sulaim and sleep on her bed while she was not there. One day, he came and someone informed her that the Prophet ﷺ was on her bed. She hurried to him and found him sweating heavily due to the intense heat. She took a bottle and started collecting his sweat in it. The Prophet ﷺ woke up and asked her what she was doing. She replied, "I am collecting your sweat, O Messenger of Allah, to use it as a perfume." The Prophet ﷺ said, "You have done right."  

كَانَ رَسُولُ اللهِ ﷺ يَدْخُلُ بَيْتَ أُمِّ سُلَيْمٍ وَيَنَامُ عَلَى فِرَاشِهَا وَلَيْسَتْ ثَمَّ قَالَ فَأَتَتْ يَوْمًا فَقِيلَ لَهَا هُوَ هَذَا رَسُولُ اللهِ ﷺ عَلَى فِرَاشِكِ فَانْتَهَتْ إِلَيْهِ وَقَدْ عَرِقَ عَرَقًا شَدِيدًا وَذَلِكَ فِي الْحَرِّ فَأَخَذَتْ قَارُورَةً فَجَعَلَتْ تَأْخُذُ مِنْ ذَلِكَ الْعَرَقِ فَجَعَلَتْهُ فِي الْقَارُورَةِ فَاسْتَيْقَظَ رَسُولُ اللهِ ﷺ فَقَالَ مَا تَصْنَعِينَ؟ فَقَالَتْ بَرَكَتُكَ يَا رَسُولَ اللهِ نَجْعَلُهُ فِي طِيبِنَا فَقَالَ رَسُولُ اللهِ ﷺ أَصَبْتِ
