O people, eat of what is lawful and clean in the earth and do not follow the ways of Satan, for he is your avowed enemy. 168 He only orders you to evil and immorality and to say about Allah what you do not know. 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 believers, eat of the good things wherewith We have provided you, and give thanks to God, if it be Him that you serve. 172 Forbidden to you are carrion and blood, and the flesh of the swine, and that which has been consecrated (or killed) in the name of any other than God. If one is obliged by necessity to eat it without intending to transgress, or reverting to it, he is not guilty of sin; for God is forgiving and kind. 173 Those who conceal Allah's revelations in the Book, and purchase for them a miserable profit, they swallow into themselves naught but Fire; Allah will not address them on the Day of Resurrection, nor purify them: Grievous will be their penalty. 174 Those are the ones who have exchanged guidance for error and forgiveness for punishment. How patient they are in pursuit of 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
