O men, eat only the things of the earth that are lawful and good. Do not walk in the footsteps of Satan, your acknowledged enemy. 168 He tries to make you do evil and shameful things and speak against God without knowledge. 169 When it is said to them: "Follow what God has revealed," they reply: "No, we shall follow only what our fathers had practiced," -- even though their fathers had no wisdom or guidance! 170 The semblance of the infidels is that of a man who shouts to one that cannot hear more than a call and a cry. They are deaf, dumb and blind, and they fail to understand. 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 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 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 revealed the Book with the truth; and surely those who go against the Book are in a great opposition. 176
