Quran 2.173-174
He hath forbidden you only carrion, and blood, and swineflesh, and that which hath been immolated to (the name of) any other than Allah. But he who is driven by necessity, neither craving nor transgressing, it is no sin for him. Lo! Allah is Forgiving, Merciful. Lo! those who hide aught of the Scripture which Allah hath revealed and purchase a small gain therewith, they eat into their bellies nothing else than fire. Allah will not speak to them on the Day of Resurrection, nor will He make them grow. Theirs will be a painful doom.
