وَحَدَّثَنَا مَالِكٌ، عَنْ عَبْدِ اللَّهِ بْنِ يَزِيدَ، مَوْلَى الأَسْوَدِ بْنِ سُفْيَانَ عَنْ أَبِي سَلَمَةَ بْنِ عَبْدِ الرَّحْمَنِ، وَعَنْ مُحَمَّدِ بْنِ عَبْدِ الرَّحْمَنِ بْنِ ثَوْبَانَ، عَنْ أَبِي هُرَيْرَةَ، أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم قَالَ ‏"‏ إِذَا اشْتَدَّ 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 ‏"‏ ‏.‏

Malik related to us from Abdullah ibn Yazid the mawla of al-Aswadibn Sufyan, from Abu Salama ibn Abd ar-Rahman from Muhammad ibn Abdar-Rahman ibn Thawban from Abu Hurayra that the Messenger of Allah,may Allah bless him and grant him peace, said, "When the heat isfierce delay the prayer until it gets cooler, for scorching heat is apart of the blast of Jahannam." He added, "The Firecomplained to its Lord, so He allowed it two breaths in each year, abreath in winter and a breath in summer." Translation Not Available
