Punishment with hot stones of hell
There is a Hadith in this regard:
Translation: It has been narrated on the authority of Hadhrat Ahnaf bin Qais (May Allah be well pleased with him), he says: I came to Madina. I sat in a group in which there were chiefs of Quraish. Suddenly a person who was wearing coarse clothes came to them. He was dignified and his face was awe-inspiring. He stood near them and said: Give tidings of that stone to those who hoard wealth, which will be heated in the fire of hell and that stone will be placed on their nipples, which will then burst from the bones of the shoulder and it will be placed on the shoulder and it will burst out through the nipple and that stone will continue going through and through like that.
The narrator says: Those people lowered their heads and I didn’t see any one of them answering to Him. (Sahih Muslim, Hadith No. 2353)
