"The Messenger of Allah, forbade selling or buying singing girls, and their wages, and consuming their price."
Sunan Ibn Majah Book 12, Hadith 32
← Previous Hadith I heard Jabir bin 'Abdullah say: "In the Year of the Conquest, while he was in Makkah the Messenger of Allah (ﷺ), said: 'Allah and His Messenger have forbidden the sale of wines, meat of dead animals, pigs and 'idols.' It was said to him: 'O Messenger of Allah, what do you think of the fat of dead animals, for it is used to caulk ships, it is daubed on animal skins and people use it to light their lamps?' He said: 'No, it is unlawful.' Then the Messenger of Allah (ﷺ) said: 'May Allah curse the jews, for Allah forbade them the fat (of animals) but they rendered it, (i.e. melted it) sold it and consumed its price."'
