O men, eat of what is in the earth lawful and good; and follow not the steps of Satan; he is a manifest foe to you. 168 For he commands you what is evil and shameful, and that ye should say of Allah that of which ye have no knowledge. 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 And the example of those who disbelieve, is as that of him who shouts to the (flock of sheep) that hears nothing but calls and cries. (They are) deaf, dumb and blind. So they do not understand. 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 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 Surely those who conceal any part of the Book that Allah has revealed and take for it a small price, they eat nothing but fire into their bellies, and Allah will not speak to them on the day of resurrection, nor will He purify them, and they shall have a painful chastisement. 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 (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
