Arabic (Original)
وَبِإِسْنَادِهِ سَمِعْتُ أَبَا الْقَاسِمِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ يَقُولُ نَارُ بَنِي آدَمَ الَّتِي يُوقِدُونَ جُزْءٌ مِنْ سَبْعِينَ جُزْءًا مِنْ نَارِ جَهَنَّمَ فَقَالَ رَجُلٌ إِنْ كَانَتْ لَكَافِيَةً فَقَالَ لَقَدْ فُضِّلَتْ عَلَيْهِ بِتِسْعَةٍ وَسِتِّينَ جُزْءًا حَرًّا فَحَرًّا.
English Translation
And with his chain: I heard Abu al-Qasim (peace and blessings be upon him) say: 'The fire that the sons of Adam kindle is one part out of seventy parts of the fire of Hell.' A man said: 'It would surely have been enough [as it is]!' He said: 'It has been made to exceed it by sixty-nine parts, each one hotter than the last.'
