Sura 2:171-173
2:171. The parable of those who reject Faith is as if one were to shout like a goat-herd, to things that listen to nothing but calls and cries: deaf, dumb, and blind, they are void of Wisdom.
2:172. O ye who believe! Eat of the good things that We have provided for you, and be grateful to God, if it is Him ye worship.
2:173. He hath only forbidden you dead meat, and blood, and the flesh of swine, and that on which any other name hath been invoked besides that of God. But if one is forced by necessity, without willful disobedience, nor transgressing due limits,- then is he guiltless. For God is Oft-forgiving Most Merciful.
