O mankind, eat from whatever is on earth [that is] lawful and good and do not follow the footsteps of Satan. Indeed, he is to you a clear enemy. 168 He tries to make you do evil and shameful things and speak against God without knowledge. 169 When it is said to them: "Follow what Allah has sent down." They say: "Nay! We shall follow what we found our fathers following." (Would they do that!) Even though their fathers did not understand anything nor were they guided? 170 And so, the parable of those who are bent on denying the truth is that of the beast which hears the shepherd's cry, and hears in it nothing but the sound of a voice and a call. Deaf are they, and dumb, and blind: for they do not use their reason. 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 He hath forbidden you only carrion, and blood, and swineflesh, and that which hath been immolated to (the name of) any other than Allah. But he who is driven by necessity, neither craving nor transgressing, it is no sin for him. Lo! Allah is Forgiving, Merciful. 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 they who have purchased error at the price of Guidance, and torment at the price of Forgiveness. So how bold they are (for evil deeds which will push them) to 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
