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 enjoineth upon you only the evil and the foul, and that ye should tell concerning Allah that which ye know not. 169 When it is said to them: "Follow what God has revealed," they reply: "No, we shall follow only what our fathers had practiced," -- even though their fathers had no wisdom or guidance! 170 The semblance of the infidels is that of a man who shouts to one that cannot hear more than a call and a cry. They are deaf, dumb and blind, and they fail to understand. 171 O ye who believe! Eat of the good things that We have provided for you, and be grateful to Allah, if it is Him 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 Verily, those who conceal what Allah has sent down of the Book, and purchase a small gain therewith (of worldly things), they eat into their bellies nothing but fire. Allah will not speak to them on the Day of Resurrection, nor purify them, and theirs will be a painful torment. 174 They are the people who purchased error in exchange of guidance, and torment in exchange of pardon; so how much can they bear the fire? 175 That is because God has revealed the Book containing the truth; but those who are at variance about it have gone astray in their contrariness. 176
