[Machine] We used to pray the Dhuhr prayer with the Messenger of Allah ﷺ in Al-Hajirah. He said to us, "Cool yourselves with prayer, for the intensity of the heat is from the exhaled breath of Hellfire." Abu Isa At-Tirmidhi, in what has been reported to me from him, said: I asked Muhammad, meaning Al-Bukhari, about this hadith, and he considered it reliable and said.  

كُنَّا نُصَلِّي مَعَ رَسُولِ اللهِ ﷺ صَلَاةَ الظُّهْرِ بِالْهَاجِرَةِ فَقَالَ لَنَا أَبْرِدُوا بِالصَّلَاةِ فَإِنَّ شِدَّةَ الْحَرِّ مِنْ فَيْحِ جَهَنَّمَ قَالَ أَبُو عِيسَى التِّرْمِذِيُّ فِيمَا بَلَغَنِي عَنْهُ سَأَلْتُ مُحَمَّدًا يَعْنِي الْبُخَارِيَّ عَنْ هَذَا الْحَدِيثِ فَعَدَّهُ مَحْفُوظًا وَقَالَ  

[Machine] You are in a hot town, so cool down on people, then cool down two or three times, then make the call to prayer, then go down and perform two rak'ahs, then cover your residence.  

إِنَّكَ فِي بَلْدَةٍ حَارَّةٍ فَأَبْرِدَ عَلَى النَّاسِ ثُمَّ أَبْرِدْ مَرَّتَيْنِ أَوْ ثَلَاثًا ثُمَّ أَذِّنْ ثُمَّ انْزِلْ فَارْكَعْ رَكْعَتَيْنِ ثُمَّ ثَوِّبْ إِقَامَتَكَ
