O mankind! Eat from what is lawful and clean in the earth; and do not follow the footsteps of the devil; undoubtedly he is your open enemy. 168 he orders you to commit evil and indecency and to assert about Allah what you do not know. 169 And when it said unto them: follow that which Allah hath sent down, they say: nay, we shall follow that way whereon we found our fathers - even though their fathers understood not aught, nor were they guided aright? 170 Preaching to unbelievers is like talking to someone who cannot hear anything except yells and shouts. They are deaf, dumb, and blind; they have no understanding. 171 Believers, eat the wholesome things which We have provided for you and give thanks to God, if it is Him you worship. 172 He has forbidden to you only carrion, and blood, and the flesh of swine, and that over which any name other than God's has been invoked; but if one is driven by necessity - neither coveting it nor exceeding his immediate need - no sin shall be upon him: for, behold, God is much-forgiving, a dispenser of grace. 173 Indeed those, who conceal the Commands that Allah has sent down in His Book and barter them away for paltry worldly gains, fill their bellies with fire. Allah will not speak to them on the Day of Resurrection, nor will He regard them as pure; "a there is a painful torment for them. 174 It is they who take error in exchange for guidance, and suffering in exchange for forgiveness: yet how little do they seem to fear the fire! 175 That is [deserved by them] because Allah has sent down the Book in truth. And indeed, those who differ over the Book are in extreme dissension. 176
