Sahih Muslim Book - 5, Hadith - 1403

وَحَدَّثَنِى حَرْمَلَةُ بْنُ يَحْيَى حَدَّثَنَا عَبْدُ اللَّهِ بْنُ وَهْبٍ أَخْبَرَنَا حَيْوَةُ قَالَ حَدَّثَنِى يَزِيدُ بْنُ عَبْدِ اللَّهِ بْنِ أُسَامَةَ بْنِ الْهَادِ عَنْ مُحَمَّدِ بْنِ إِبْرَاهِيمَ عَنْ أَبِى سَلَمَةَ عَنْ أَبِى هُرَيْرَةَ عَنْ رَسُولِ اللَّهِ -صلى الله عليه وسلم- قَالَ « قَالَتِ النَّارُ رَبِّ أَكَلَ بَعْضِى بَعْضًا فَأْذَنْ لِى أَتَنَفَّسْ. فَأَذِنَ لَهَا بِنَفَسَيْنِ نَفَسٍ فِى الشِّتَاءِ وَنَفَسٍ فِى الصَّيْفِ فَمَا وَجَدْتُمْ مِنْ بَرْدٍ أَوْ زَمْهَرِيرٍ فَمِنْ نَفَسِ جَهَنَّمَ وَمَا وَجَدْتُمْ مِنْ حَرٍّ أَوْ حَرُورٍ فَمِنْ نَفَسِ جَهَنَّمَ ».

It was narrated from Abu Hurairah that the Messenger of Allah (s.a.w) said: "The Fire said: 'Lord, parts of me have consumed other parts; give me permission to breathe out.' So He gave it permission to breathe out, once in the winter and once in the summer. What you experience of cold, or intense cold, is the breath of Hell, and what you experience of heat or intense heat is the breath of Hell.''
