Sayyiduna Jabir bin Abdullah (may Allah be pleased with both of them) reports that the Messenger of Allah (peace and blessings be upon him) said:“Allah Almighty has forbidden the sale and purchase of alcohol, idols, carrion, and swine.”One of the Muslims asked:“What is your opinion about the fat of carrion? It is used to tan hides and to paint boats, and people also use it to light lamps.”The Prophet (peace and blessings be upon him) replied:“It is forbidden. May Allah destroy the Jews; when fat was made unlawful for them, they melted it down, sold it, and consumed its price.”
