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 He bids you only to do evil and to commit deeds of abomination and to attribute to God something of which you have no knowledge. 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 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 VERILY, as for those who suppress aught of the revelation which God has bestowed from on high, and barter it away for a trifling gain - they but fill their bellies with fire. And God will not speak unto them on the Day of Resurrection, nor will He cleanse them [of their sins]; and grievous suffering awaits them. 174 These are they who have purchased error for guidance, and torment for forgiveness. How enduring must they be of the Fire! 175 That is [deserved by them] because Allah has sent down the Book in truth. And indeed, those who differ over the Book are in extreme dissension. 176
