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 only enjoins you evil and indecency, and that you may speak against Allah what you do not know. 169 When it is said to them, "Follow the Commands that Allah has sent down," they reply, "We will follow only what we found our forefathers practising., Well, will they go on following their forefathers even though they did not use common sense and did not find the right way? 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 Believers, eat of the good with which We have provided you and give thanks to Allah, if you really worship Him. 172 Allah has only forbidden you to eat what dies of itself, and blood and swine flesh and what has been consecrated to any other name than of Allah. But one will incur no sin if, forced by absolute necessity, he eats of any of these forbidden things, provided he has no intention of transgressing the law and does not take more than what is absolutely indispensable: for Allah is very Forgiving and very 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 Such are those who buy error for guidance, and punishment for pardon. How patiently they will be in the Fire. 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
