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 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 The likeness of those who disbelieve is as the likeness of one who shouts to that which hears nothing, save a call and a cry; deaf, dumb, blind -- they do not understand. 171 Believers, eat the wholesome things which We have provided for you and give thanks to God, if it is Him you worship. 172 Forbidden to you are carrion and blood, and the flesh of the swine, and that which has been consecrated (or killed) in the name of any other than God. If one is obliged by necessity to eat it without intending to transgress, or reverting to it, he is not guilty of sin; for God is forgiving and kind. 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 Such are those who buy error for guidance, and punishment for pardon. How patiently they will be in 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
