O mankind! Eat of that which is lawful and wholesome in the earth, and follow not the footsteps of the devil. Lo! he is an open enemy for you. 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 O you who believe! eat of the good things that We have provided you with, and give thanks to Allah if Him it is that you serve. 172 God has forbidden you to eat that which has not been properly slaughtered, blood, pork, and the flesh of any animal which has not been consecrated with a mention of the Name of God. However, in an emergency, without the intention of transgression or repeating transgression, one will not be considered to have committed a sin. God is All-forgiving and All-merciful. 173 Indeed those, who conceal the Commands that Allah has sent down in His Book and barter them away for paltry worldly gains, fill their bellies with fire. Allah will not speak to them on the Day of Resurrection, nor will He regard them as pure; "a there is a painful torment for them. 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 That, because God has sent down the Book with the truth; and those that are at variance regarding the Book are in wide schism. 176
