Mankind! eat of whatsoever is in the earth, lawful and clean, and follow not the footsteps of Satan; verily he is an enemy unto you manifest. 168 He enjoineth upon you only the evil and the foul, and that ye should tell concerning Allah that which ye know not. 169 And when it is said to them, "Follow what Allah has revealed," they say, "Rather, we will follow that which we found our fathers doing." Even though their fathers understood nothing, nor were they guided? 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 you who believe (in the Oneness of Allah - Islamic Monotheism)! Eat of the lawful things that We have provided you with, and be grateful to Allah, if it is indeed He Whom you 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 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 This was inspite of the fact that Allah had sent down the Book with the Truth but the people who sought differences in the Book swerved far away from the Truth in their disputes. 176
