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 But when they are told, "Follow what God has bestowed from on high," some answer, "Nay, we shall follow [only] that which we found our forefathers believing in and doing." Why, even if their forefathers did not use their reason at all, and were devoid of all guidance? 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 the wholesome things which We have provided for you and give thanks to God, if it is Him 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 Indeed, they who conceal what Allah has sent down of the Book and exchange it for a small price - those consume not into their bellies except the Fire. And Allah will not speak to them on the Day of Resurrection, nor will He purify them. And they will have a painful punishment. 174 They are the people who have bartered away Guidance for error and Allah's pardon for His punishment. How audacious they are: they are ready even to endure the fire of Hell. 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
