"This Fire of yours, which the sons of Adam kindle, is one part from seventy parts of the heat of the Hell." They said: "By Allah! Would it not have been enough O Messenger of Allah?!" He said: "It is sixty-nine parts more – all of them similar in heat.” (Sahih)

عَنِ النَّبِيِّ ﷺ قَالَ نَارُكُمْ هَذِهِ الَّتِي يُوقِدُ بَنُو آدَمَ جُزْءٌ وَاحِدٌ مِنْ سَبْعِينَ جُزءًا مِنْ حَرِّ جَهَنَّمَ قَالُوا وَاللَّهِ إِنْ كَانَتْ لَكَافِيَةً يَا رَسُولَ اللَّهِ قَالَ فَإِنَّهَا فُضِّلَتْ بِتِسْعَةٍ وَسِتِّينَ جُزْءًا كُلُّهُنَّ مِثْلُ حَرِّهَا
