Narrated by:Abu Hurairah said
It was narrated that Abu Hurairah said:"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.'"
حَدَّثَنَا هِشَامُ بْنُ عَمَّارٍ، حَدَّثَنَا مَالِكُ بْنُ أَنَسٍ، حَدَّثَنَا أَبُو الزِّنَادِ، عَنِ الأَعْرَجِ، عَنْ أَبِي هُرَيْرَةَ، قَالَ قَالَ رَسُولُ اللَّهِ ـ صلى الله عليه وسلم ـ " إِذَا اشْتَدَّ الْحَرُّ فَأَبْرِدُوا بِالصَّلاَةِ فَإِنَّ شِدَّةَ الْحَرِّ مِنْ فَيْحِ جَهَنَّمَ " .
