When it is said to them: "Follow what Allah has sent down." They say: "Nay! We shall follow what we found our fathers following." (Would they do that!) Even though their fathers did not understand anything nor were they guided?" (2:170)

Forbidden to you (for food) are: Al-Maytatah (the dead animals - cattle-beast not slaughtered), blood, the flesh of swine, and the meat of that which has been slaughtered as a sacrifice for others than Allah, or has been slaughtered for idols, etc., or on which Allah's Name has not been mentioned while slaughtering, and that which has been killed by strangling, or by a violent blow, or by a headlong fall, or by the goring of horns - and that which has been (partly) eaten by a wild animal - unless you are able to slaughter it (before its death) ­ and that which is sacrificed (slaughtered) on An­Nusub[] (stone altars). (Forbidden) also is to use arrows seeking luck or decision, (all) that is Fisqun (disobedience of Allah and sin). This day, those who disbelieved have given up all hope of your religion, so fear them not, but fear Me. This day, I have perfected your religion for you, completed My Favour upon you, and have chosen for you Islam as your religion. But as for him who is forced by severe hunger, with no inclination to sin (such can eat these above-mentioned meats), then surely, Allah is Oft­Forgiving, Most Merciful." (5:3)

And when it is said to them: "Come to what Allah has revealed and unto the Messenger (Muhammad SAW for the verdict of that which you have made unlawful)." They say: "Enough for us is that which we found our fathers following," even though their fathers had no knowledge whatsoever and no guidance." (5:104)

And according to their pretending, they say that such and such cattle and crops are forbidden, and none should eat of them except those whom we allow. And (they say) there are cattle forbidden to be used for burden or any other work, and cattle on which (at slaughtering) the Name of Allah is not pronounced; lying against Him (Allah). He will recompense them for what they used to fabricate." (6:138)
