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 And when it is said to them, "Follow what Allah has revealed," they say, "Rather, we will follow that which we found our fathers doing." Even though their fathers understood nothing, 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 Believers, eat from the good things that We have given you and give thanks to God if you worship only Him. 172 He has forbidden you the dead, blood, and the flesh of swine, also that which is invoked to other than Allah. But whoever is constrained (to eat) any of these, not intending to sin or transgress, incurs no guilt. Allah is Forgiving and the Most 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 They have exchanged guidance for error and forgiveness for torment. What makes them seek the fire so earnestly (for they are doomed to be punished)? 175 God has revealed the Book in all Truth and those who dispute it are filled with malice which has taken them far away from the truth. 176
