Musannaf Ibn Abi Shaybah 36844 — Reports on what is prepared

It is narrated from Ubayd bin Umayr that the Messenger of Allah (peace and blessings be upon him) said: "The least punishment in Hell will be for the person who will be made to wear shoes of fire, because of which his brain will boil as though it were a cauldron. His ears will be of embers, his molars will be of embers, his eyelids will be flames of fire, and the entrails of his sides will come out through his feet. The rest of them will be like a few grains in much water, which keeps boiling."
