سنن النسائي

It was narrated from Jabir bin 'Abdullah that he heard the Messenger of Allah (ﷺ) say, when he was in Makkah during the Year of the Conquest: "Allah and His Messenger have forbidden the sale of wine, dead animals, pigs and idols." It was said: "O messenger of Allah, what do you thing about the fat of the dead animal, for ships are caulked with it, skins are daubed with it and people use it in their lamps." He said: "No, it is Haram." And the Messenger of Allah (ﷺ) then said: "My Allah curse the Jews, for when Allah, the Mighty and Sublime, forbade the meat (of dead animals) to them, they melted it down and sold it, and consumed its price."
