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 For he commands you what is evil and shameful, and that ye should say of Allah that of which ye have no knowledge. 169 And when it is said to them, 'Follow what God has sent down,' they say, 'No; but we will follow such things as we found our fathers doing.' What? And if their fathers had no understanding of anything, and if they were not 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 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, 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 Such are those who buy error for guidance, and punishment for pardon. How patiently they will be in the Fire. 175 That is because Allah has sent down the Book with the truth; those who disagree about it are in extreme dissension. 176
