Abu Huraira reported:

The Messenger of Allah (ﷺ) said: When it is hot, make delay (in the noon prayer) till it cools down, for the intensity of beat is from the Exhalation of Hell; and he also mentioned that Hellfire complained to the Lord (about the congested atmosphere) and so it was permitted to take two exhalations during the whole year, one exhalation during the winter and one exhalation during the summer.

وَحَدَّثَنِي إِسْحَاقُ بْنُ مُوسَى الأَنْصَارِيُّ، حَدَّثَنَا مَعْنٌ، حَدَّثَنَا مَالِكٌ، عَنْ عَبْدِ اللَّهِ بْنِ يَزِيدَ، مَوْلَى الأَسْوَدِ بْنِ سُفْيَانَ عَنْ أَبِي سَلَمَةَ بْنِ عَبْدِ الرَّحْمَنِ، وَمُحَمَّدِ بْنِ عَبْدِ الرَّحْمَنِ بْنِ ثَوْبَانَ، عَنْ أَبِي هُرَيْرَةَ، أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم قَالَ ‏"‏ إِذَا كَانَ الْحَرُّ فَأَبْرِدُوا عَنِ الصَّلاَةِ فَإِنَّ شِدَّةَ الْحَرِّ مِنْ فَيْحِ جَهَنَّمَ ‏"‏ ‏.‏ وَذَكَرَ ‏"‏ أَنَّ النَّارَ اشْتَكَتْ إِلَى رَبِّهَا فَأَذِنَ لَهَا فِي كُلِّ عَامٍ بِنَفَسَيْنِ نَفَسٍ فِي الشِّتَاءِ وَنَفَسٍ فِي الصَّيْفِ ‏"‏ ‏.‏
