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 tries to make you do evil and shameful things and speak against God without knowledge. 169 But when they are told, "Follow what God has bestowed from on high," some answer, "Nay, we shall follow [only] that which we found our forefathers believing in and doing." Why, even if their forefathers did not use their reason at all, and were devoid of all guidance? 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 good things wherewith We have provided you, and render thanks to Allah if it is (indeed) He Whom ye worship. 172 He has forbidden you only carrion, blood, and the flesh of swine; also any flesh that is consecrated other than in the name of God. But for one who is driven by necessity, neither craving nor transgressing, it is no sin. For God is forgiving and merciful. 173 Those who conceal what Allah has sent down of the Book and sell it for a small price shall swallow nothing but fire into their bellies. On the Day of Resurrection, Allah will neither speak to them nor purify them. Theirs shall be a painful punishment. 174 They are those who bartered away good guidance for error, and pardon for punishment: How great is their striving for the Fire 175 This is because Allah has sent down the Book with the truth; and indeed those who caused disagreement in the Book are, surely, disputants in the extreme. 176
