The prohibited foods and meat are detailed in 2:173, 5:3, 6:145 and 16:115. From these verses we have a clear account of what is halal (lawful) and what is haram (prohibited). He only prohibited for you carrion, blood, the flesh of the pig and what was dedicated to other than God, but if one is forced out of necessity rather than desire or greed, then he incurs no sin. God is Forgiver, Merciful. 2:173. Further prohibited animals, listed in 5:3, are those strangled, struck with an object, fallen from a height, gored, attacked by a wild animal, unless the animal is saved before it dies. Also prohibited are animals sacrificed on altars.
