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 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 Those who deny the truth are like animals which hear nothing in your call but the sound of a voice, without understanding its meaning. They are deaf, dumb and blind. They understand nothing. 171 O you who have attained to faith! Partake of the good things which We have provided for you as sustenance, and render thanks unto God, if it is [truly] Him that you worship. 172 He hath forbidden you only carrion, and blood, and swineflesh, and that which hath been immolated to (the name of) any other than Allah. But he who is driven by necessity, neither craving nor transgressing, it is no sin for him. Lo! Allah is Forgiving, Merciful. 173 Those who hide the Book sent down by Allah and exchange it for an abject price – they only fill their bellies with fire and Allah will not speak to them on the Day of Resurrection nor will He purify them; and for them is a painful punishment. 174 They are those who bartered away good guidance for error, and pardon for punishment: How great is their striving for the Fire 175 That is because God has revealed the Book containing the truth; but those who are at variance about it have gone astray in their contrariness. 176
