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 enjoineth upon you only the evil and the foul, and that ye should tell concerning Allah that which ye know not. 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 believers, eat what is good of the food We have given you, and be grateful to God, if indeed you are obedient to Him. 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 Surely those who conceal any part of the Book that Allah has revealed and take for it a small price, they eat nothing but fire into their bellies, and Allah will not speak to them on the day of resurrection, nor will He purify them, and they shall have a painful chastisement. 174 These are they who buy error for the right direction and chastisement for forgiveness; how bold they are to encounter fire. 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
