Hadith 59:75
Narrated Abu Huraira:
Allah's Messenger (ﷺ) said, "Your (ordinary) fire is one of 70 parts of the (Hell) Fire." Someone asked, "O Allah's Messenger (ﷺ) This (ordinary) fire would have been sufficient (to torture the unbelievers)," Allah's Apostle said, "The (Hell) Fire has 69 parts more than the ordinary (worldly) fire, each part is as hot as this (worldly) fire."
حَدَّثَنَا إِسْمَاعِيلُ بْنُ أَبِي أُوَيْسٍ، قَالَ حَدَّثَنِي مَالِكٌ، عَنْ أَبِي الزِّنَادِ، عَنِ الأَعْرَجِ، عَنْ أَبِي هُرَيْرَةَ ـ رضى الله عنه ـ أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم قَالَ " نَارُكُمْ جُزْءٌ مِنْ سَبْعِينَ جُزْءًا مِنْ نَارِ جَهَنَّمَ ". قِيلَ يَا رَسُولَ اللَّهِ، إِنْ كَانَتْ لَكَافِيَةً. قَالَ " فُضِّلَتْ عَلَيْهِنَّ بِتِسْعَةٍ وَسِتِّينَ جُزْءًا، كُلُّهُنَّ مِثْلُ حَرِّهَا "
