حَدَّثَنَا مُحَمَّدُ بْنُ رُمْحٍ، أَنْبَأَنَا اللَّيْثُ بْنُ سَعْدٍ، عَنِ ابْنِ شِهَابٍ، عَنْ سَعِيدِ بْنِ الْمُسَيَّبِ، وَأَبِي، سَلَمَةَ بْنِ عَبْدِ الرَّحْمَنِ عَنْ أَبِي هُرَيْرَةَ، أَنَّ رَسُولَ اللَّهِ ـ صلى الله عليه وسلم ـ قَالَ ‏"‏ إِذَا اشْتَدَّ الْحَرُّ فَأَبْرِدُوا بِالظُّهْرِ فَإِنَّ شِدَّةَ الْحَرِّ مِنْ فَيْحِ جَهَنَّمَ ‏"‏ ‏.‏

It was narrated from Abu Hurairah that: The Messenger of Allah said: "When it is very hot, then wait for it to cool down before you pray, for intense heat is from the flaring up of the Hell-fire." Translation Not Available
