وَعَنِ النُّعْمَانِ بْنِ بَشِيرٍ قَالَ: قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ: «إِنَّ أَهْوَنَ أَهْلِ النَّارِ عَذَابًا مَنْ لَهُ نَعْلَانِ وَشِرَاكَانِ مِنْ نَارٍ يَغْلِي مِنْهُمَا دِمَاغُهُ كَمَا يَغْلِي الْمِرْجَلُ مَا يُرَى أَنَّ أَحَدًا أَشَدُّ مِنْهُ عَذَابًا وَإِنَّهُ لَأَهْوَنُهُمْ عَذَابًا» . مُتَّفق عَلَيْهِ

An-Nu`man b. Bashir reported God’s messenger as saying, “The inhabitant of hell who will have the lightest punishment will be he who has two sandals and two sandal-straps of fire from which his brain will bubble like a pot, and he will think that no one is having a more severe punishment than he, although he is having the lightest punishment.” (Bukhari and Muslim;)
