Hadith 31:16
Abu Usama narrated to us, from al-A'mash, from Abu Ishaq, from al-Nu'man ibn Bashir, who said: The Messenger of Allah (peace and blessings of Allah be upon him) said: "The person among the people of the Fire with the lightest punishment is he who has two sandals and two straps of fire, from which his brain boils just as a cooking pot boils. He does not think that anyone is in a more severe punishment than him, yet he is the lightest of them in punishment."
حدثنا أبو أسامة عن الأعمش عن أبي إسحاق عن النعمان بن بشير قال قال رسول الله صلى الله عليه وسلم إن أهون أهل النار عذابا من له نعلان وشراكان من نار يغلي منهما دماغه كما يغلي المرجل ما يرى أن أحدا أشد عذابا منه وإنه لأهونهم عذابا
