O MANKIND! Partake of what is lawful and good on earth, and follow not Satan's footsteps: for, verily, he is your open foe, 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 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 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 believers, eat what is good of the food We have given you, and be grateful to God, if indeed you are obedient to Him. 172 These things only has He forbidden you: carrion, blood, the flesh of swine, what has been hollowed to other than God. Yet who so is constrained, not desiring nor transgressing, no sin shall be on him; God is All-forgiving, All-compassionate. 173 Those who conceal any part of the Scriptures that God has revealed, and thus make a little profit thereby, take nothing but fire as food; and God will not turn to them on the Day of Resurrection, nor nourish them for growth; and their doom will be painful. 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 This is because Allah has sent down the Book with the truth; and indeed those who caused disagreement in the Book are, surely, disputants in the extreme. 176
