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 enjoineth upon you only the evil and the foul, and that ye should tell concerning Allah that which ye know not. 169 But when they are told, "Follow what God has sent down," they answer, "We will follow the ways of our fathers," even though their fathers did not use their reason, and were devoid of all guidance. 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 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 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 Such are those who buy error for guidance, and punishment for pardon. How patiently they will be in the Fire. 175 That is because Allah has sent down the Book (the Quran) in truth. And verily, those who disputed as regards the Book are far away in opposition. 176
