Overall meaning : Allah, Glorified be He, directs His Prophet, Muhammad, may Allah bless him and grant him peace, to say to those who invent lies about Allah by declaring as forbidden what Allah has bestowed upon them and falsely attributing such prohibitions to Him: In all that has been revealed to me, I do not find anything forbidden to eat, as you falsely claim, except for the flesh of animals that die of themselves (that is, without being slaughtered in accordance with Islamic law or killed in a hunt), running, outpoured blood, the flesh of pigs—for all these three are indeed unclean and impure—and sacrificial animals over which the name of other than Allah is invoked upon slaughtering them, for doing any of these is an act of unbelief and disobedience to Him. However, He further states, whoever is compelled by dire necessity through hunger and eats of these forbidden things will incur no sin as long as he does not do so thereby intending to enjoy eating, nor exceed the bounds of necessity; for Allah is indeed All-Forgiving, All-Merciful.
The Almighty also states that He forbade the Jews the flesh of all animals with claws (such as ostriches and ducks), and in respect of cattle, sheep and goats, He forbade them their fat except what adheres to their backs, the entrails, or is mixed up with their bones (such as the rump fat). Such restrictions, He explains, were imposed on them as punishment for their disobedience and for transgressing His limits, stating that everything He says, does or decrees is the truth.
Then, addressing His Prophet, may Allah bless him and grant him peace, He says: If they deny you and call you a liar, say to them that their Lord’s mercy is all-embracing for those who obey Him, and so they should hasten to attain it by utilising the means leading to it. Part of His mercy is that He does not hasten to inflict punishment on them for their sins but gives them respite so they may turn to Him in repentance. He also enjoins him to say to them that His punishment cannot be averted from the wicked sinners. Thus, they should beware of sins leading to His punishment, foremost of which is denying Muhammad, may Allah bless him and grant him peace.
