حَدَّثَنِي مَالِكٌ، عَنْ أَبِي الزِّنَادِ، عَنِ الأَعْرَجِ، عَنْ أَبِي هُرَيْرَةَ، أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم قَالَ ‏"‏ نَارُ بَنِي آدَمَ الَّتِي يُوقِدُونَ جُزْءٌ مِنْ سَبْعِينَ جُزْءًا مِنْ نَارِ جَهَنَّمَ ‏"‏ ‏.‏ فَقَالُوا يَا رَسُولَ اللَّهِ إِنْ كَانَتْ لَكَافِيَةً ‏.‏ قَالَ ‏"‏ إِنَّهَا فُضِّلَتْ عَلَيْهَا بِتِسْعَةٍ وَسِتِّينَ جُزْءًا ‏"‏ ‏.‏

Malik related to me from Abu'z-Zinad from al-Araj from AbuHurayra that the Messenger of Allah, may Allah bless him and grant himpeace, said, "The fire of the children of Adam which they kindle is aseventieth part of the fire of Jahannam." They said, "Messenger ofAllah, this fire is certainly enough." He said, "That fire is sixty-nine times greater." Translation Not Available
