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 and bids you only to do evil, and to commit deeds of abomination, and to attribute unto God something of which you have no knowledge. 169 And when it is said unto them: Follow that which Allah hath revealed, they say: We follow that wherein we found our fathers. What! Even though their fathers were wholly unintelligent and had no guidance? 170 And so, the parable of those who are bent on denying the truth is that of the beast which hears the shepherd's cry, and hears in it nothing but the sound of a voice and a call. Deaf are they, and dumb, and blind: for they do not use their reason. 171 O Believers, if you are true worshippers of Allah alone, eat without hesitation of the good and clean things wherewith We have provided you and be grateful to Allah. 172 Forbidden to you are carrion and blood, and the flesh of the swine, and that which has been consecrated (or killed) in the name of any other than God. If one is obliged by necessity to eat it without intending to transgress, or reverting to it, he is not guilty of sin; for God is forgiving and kind. 173 VERILY, as for those who suppress aught of the revelation which God has bestowed from on high, and barter it away for a trifling gain - they but fill their bellies with fire. And God will not speak unto them on the Day of Resurrection, nor will He cleanse them [of their sins]; and grievous suffering awaits them. 174 These are they who have purchased error for guidance, and torment for forgiveness. How enduring must they be of the Fire! 175 That is [deserved by them] because Allah has sent down the Book in truth. And indeed, those who differ over the Book are in extreme dissension. 176
