Sahih Muslim · Book 1: The Book of Faith · The least severely punished of the people of the Fire
Abu Sa'id al-Khudri reported:
حَدَّثَنَا أَبُو بَكْرِ بْنُ أَبِي شَيْبَةَ ، حَدَّثَنَا يَحْيَى بْنُ أَبِي بُكَيْرٍ ، حَدَّثَنَا زُهَيْرُ بْنُ مُحَمَّدٍ ، عَنْ سُهَيْلِ بْنِ أَبِي صَالِحٍ ، عَنِ النُّعْمَانِ بْنِ أَبِي عَيَّاشٍ ، عَنْ أَبِي سَعِيدٍ الْخُدْرِيِّ ، أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم قَالَ " إِنَّ أَدْنَى أَهْلِ النَّارِ عَذَابًا يَنْتَعِلُ بِنَعْلَيْنِ مِنْ نَارٍ يَغْلِي دِمَاغُهُ مِنْ حَرَارَةِ نَعْلَيْهِ " .
Verily, the Messenger of Allah (ﷺ) said: The least tormented of the inhabitants of the Fire would be he who would wear two shoes of Fire and his brain would boil on account of the heat of the shoes.
