It is narrated from Sayyiduna Abu Sa'id Khudri, may Allah be pleased with him, that the Messenger of Allah, peace and blessings be upon him, said: The person among the inhabitants of Hell who will have the least punishment will be the one who will be made to wear shoes of fire, due to which his brain will start boiling. Some of the inhabitants of Hell will have fire up to their ankles and along with that, they will be given additional punishment. For some, the fire will reach up to their knees and along with that, they will be given more punishment. For some, the fire will reach up to their chest and along with that, they will be given further punishment. And there will be some who will be completely immersed in fire and along with that, they will be given even more punishment.
