Malik related to me from Abu'z-Zinad from al-Araj from Abu Hurayra that the Messenger of Allah ﷺ said, "The fire of the children of Adam which they kindle is a seventieth part of the fire of Jahannam." They said, "Messenger of Allah, this fire is certainly enough." He said, "That fire is sixty- nine times greater."
أَنَّ رَسُولَ اللَّهِ ﷺ 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
