In principle, it is permissible to feed animals with unlawful meet, like the meat of a dead animal and the like, as long as this meat does not cause harm to the animal, otherwise it is forbidden to feed it with it because of the harm. However, it is forbidden to buy this kind of meat except in case of necessity even if this is with the intention of feeding what is permissible to be fed with the meat of dead animals. Jaabir narrated that the Prophet prohibited the sale of the meat of dead animals. [Al-Bukhari and Muslim] If one buys the meat of a dead animal, he is helping in sin and Allaah Says (what means): {Help you one another in virtue, righteousness and piety but do not help one another in sin and transgression.}[Quran 5:2].
