O mankind! Eat from what is lawful and clean in the earth; and do not follow the footsteps of the devil; undoubtedly he is your open 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 hath revealed:" They say: "Nay! we shall follow the ways of our fathers." What! even though their fathers Were void of wisdom and 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 believers, eat of the good things wherewith We have provided you, and give thanks to God, if it be Him 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 They are the ones who buy Error in place of Guidance and Torment in place of Forgiveness. Ah! what boldness (They show) for the Fire! 175 (Their doom is) because Allah sent down the Book in truth but those who seek causes of dispute in the Book are in a schism Far (from the purpose). 176
