O men, eat only the things of the earth that are lawful and good. Do not walk in the footsteps of Satan, your acknowledged 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 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 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 you who believe! eat of the good things that We have provided you with, and give thanks to Allah if Him it is that you serve. 172 God has forbidden you to eat that which has not been properly slaughtered, blood, pork, and the flesh of any animal which has not been consecrated with a mention of the Name of God. However, in an emergency, without the intention of transgression or repeating transgression, one will not be considered to have committed a sin. God is All-forgiving and All-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 purchase error at the price of guidance, and torment at the price of pardon. How constant are they in their strife to reach the Fire! 175 That, because God has sent down the Book with the truth; and those that are at variance regarding the Book are in wide schism. 176
