O mankind, eat whatever is lawful and wholesome on the earth; and do not follow in the footsteps of Satan; for he is indeed your avowed enemy. 168 For he commands you what is evil and shameful, and that ye should say of Allah that of which ye have no knowledge. 169 And when it is said to them, 'Follow what God has sent down,' they say, 'No; but we will follow such things as we found our fathers doing.' What? And if their fathers had no understanding of anything, and if they were not guided? 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 O Ye who believe! eat of the clean things wherewith We have provided you, and return thanks unto Allah, if Him indeed ye are wont to worship. 172 These things only has He forbidden you: carrion, blood, the flesh of swine, what has been hollowed to other than God. Yet who so is constrained, not desiring nor transgressing, no sin shall be on him; God is All-forgiving, All-compassionate. 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 They are the ones who buy Error in place of Guidance and Torment in place of Forgiveness. Ah! what boldness (They show) for the Fire! 175 (Their doom is) because Allah sent down the Book in truth but those who seek causes of dispute in the Book are in a schism Far (from the purpose). 176
