LEAST PUNISHMENT IN HELL H 399 "The one who is least punished amongst the inhabitants of the Fire will be the one who has two brands of fire under his feet and his brain boils. He will imagine himself to be the most punished person and yet he will be the least punished among them." R 399 Bukhari and Muslim with a chain up to Nu'man, the son of Bashir who related that he heard the Prophet, praise and peace be upon him, say this.
398- وعن النعمان بن بشير رضي الله عنهما ، قَالَ : سَمِعْتُ رَسُول الله صلى الله عليه وآله وسلم ، يقول : "إنَّ أهْوَنَ أهْلِ النَّارِ عَذَاباً يَوْمَ القِيَامَةِ لَرَجُلٌ يوضعُ في أخْمَصِ قَدَمَيْهِ جَمْرَتَانِ يَغْلِي مِنْهُمَا دِمَاغُهُ . مَا يَرَى أنَّ أَحَداً أشَدُّ مِنْهُ عَذَاباً ، وَأنَّهُ لأَهْوَنُهُمْ عَذَاباً" مُتَّفَقٌ عَلَيهِ .
