Muhammad bin Abi 'Adi محمد بن أبي عدي · The Book of Drinks

A man from (the tribe of) Jaishan, who are from Yemen, came and asked the Messenger of Allah said: "Every intoxicant is unlawful. Allah, the Mighty and Sublime, has promised the one who drinks intoxicants that He will give him to drink from the mud of Khibal." They said: "O Messenger of Allah, what is the mud of Khibal?" He said: "The sweat of the people of Hell," or he said: "The juice of the people of Hell."
