[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  

[Machine] That Abdullah bin Umar used to perform ablution in extreme heat, and he would pass his hands over his armpits without invalidating his ablution.  

أَنَّ عَبْدَ اللهِ بْنَ عُمَرَ كَانَ يَتَوَضَّأُ فِي الْحَرِّ فَيُمِرُّ يَدَيْهِ عَلَى إِبْطَيْهِ وَلَا يَنْقُضُ ذَلِكَ وُضُوءَهُ
