[Machine] From his statement "[Every time their skins are burnt, We will change them for fresh skins]" (Quran 4:56), Hisham said on the authority of Al-Hasan: The Fire consumes them every day seventy thousand times. Whenever it finishes consuming them and their skin is renewed, they are told to return and they do so as they were before.
عَنْ قَوْلِهِ ﷻ {كُلَّمَا نَضِجَتْ جُلُودُهُمْ بَدَّلْنَاهُمْ جُلُودًا غَيْرَهَا} [النساء 56] قَالَ هِشَامٌ عَنِ الْحَسَنِ تَأْكُلُهُ النَّارُ كُلَّ يَوْمٍ سَبْعِينَ أَلْفَ مَرَّةٍ كُلَّمَا أَكَلَتْهُمْ وَأَنْضَجَتْهُمْ قِيلَ لَهُمْ عُودُوا فَيَعُودُونَ كَمَا كَانُوا
