Messenger of Allah ﷺ said, "Your (ordinary) fire is one of 70 parts of the (Hell) Fire." Someone asked, "O Messenger of Allah 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."

أَنَّ رَسُولَ اللَّهِ ﷺ 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

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

The fire which sons of Adam burn is only one-seventieth part of the Fire of Hell. His Companions said: By Allah, even ordinary fire would have been enough (to burn people). Thereupon he said: It is sixty-nine parts in excess of (the heat of) fire in this world each of them being equivalent to their heat. (Using translation from Muslim 2843a)

أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ «نَارُكُمُ الَّتِي تُوقِدُونَ جُزْءٌ مِنْ سَبْعِينَ جُزْءًا مِنْ نَارِ جَهَنَّمَ» قَالُوا يَا رَسُولَ اللَّهِ إِنْ كَانَتْ لَكَافِيَةً قَالَ «إِنَّهَا فُضِّلَتْ عَلَيْهَا بِتِسْعَةٍ وَسِتِّينَ جُزْءًا»

"نَارُكُمْ هَذِهِ الَّتِي يُوقِدُ بَنُو آدَمَ جُزْءٌ مِنْ سَبْعِينَ جُزْءًا مِنْ نَارِ جَهَنَّمَ، قِيلَ: يَا رَسُولَ الله: إِنْ كَانَتْ لَكَافِيَةً، قَال: فَإِنَّهَا فُضِّلَتْ عَلَيهَا بِتِسْعَةٍ وَسِتِّينَ جُزْءًا كلُّهُنَّ مِثْلُ حَرِّهَا".
