It was narrated from Jabir bin ‘Abdullah that, during the year of the Conquest, while he was in Makkah he heard the Messenger of Allah صلی اللہ علیہ وآلہ وسلم say “Allah, the Mighty and Sublime, and His Messenger have forbidden the sale of alcohol, dead meat, pigs and idois.” It was said to him: “Messenger of Allah صلی اللہ علیہ وآلہ وسلم,what do you think of the fat of dead animals, for it is used to caulk ships, it is daubed animal skins, and people use it to light their lamps?” He said: “No, it is unlawful.” Then the Messenger of Allah صلی اللہ علیہ وآلہ وسلم said: “May Allah, the Mighty and Sublime, curse the Jews, for Allah forbade them the fat (of dead animals) but they rendered it, sold it and consumed its price.” (Sahih)
