[Machine] The Prophet ﷺ said, "If a piece of iron from hellfire was struck against a mountain, it would crumble into ash, just like how it is used to strike the people of fire."
أَنَّ النَّبِيَّ ﷺ قَالَ «لَوْ ضَرَبَ مِقْمَعٌ مِنْ حَدِيدِ جَهَنَّمَ الْجَبَلَ لَتَفَتَّتْ كَمَا يُضْرَبُ بِهِ أَهْلُ النَّارِ فَصَارَ رَمَادًا»
