Jabir b. 'Abdullah (Allah be pleased with them) reported Allah's Messenger ( صلی اللہ علیہ وسلم ) as saying in the Year of Victory while he was in Mecca:
Verily Allah and His Messenger have forbidden the sale of wine, carcass, swine and idols, It was said: Allah's Messenger, you see that the fat of the carcass is used for coating the boats and varnishing the hides and people use it for lighting purposes, whereupon he said: No, it is forbidden, Then Allah's Messenger ( صلی اللہ علیہ وسلم ) said: May Allah the Exalted and Majestic destroy the Jews; when Allah forbade the use of fat of the carcass for them, they melted it, and then sold it and made use of its price (received from it).
