Allah (s.w.t.) says in Holy Quran
5:3. Forbidden to you (for food) are carrion and blood and swine flesh, and that which has been dedicated to any other than Allah, and the strangled, and the dead through beating, and the dead through falling from a height, and that which has been killed by (the goring of) horns, and the devoured of wild beasts, except that which you make lawful (by the death stroke), and that which has been immolated to idols. And (forbidden is it) that you swear by the divining arrows. This is an abomination. This day are those who disbelieve in despair of (ever harming) your religion; so fear them not, fear Me! This day have I perfected your religion for you and completed My favor to you, and have chosen for you as religion AL- ISLAM. Who so is forced by hunger, not by will, to sin: (for him) surely! Allah is Forgiving, Merciful.
2:173. He has forbidden you only carrion, and blood, and swine flesh, and that which has 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. Surely! Allah is Forgiving, Merciful.
16:115. He has forbidden for you only carrion and blood and swine flesh and that which has been immolated in the name of any other than Allah;but he who is driven thereto, neither craving nor transgressing, surely!then Allah is Forgiving, Merciful.
6:146. Say: I find not in that which is revealed to me aught prohibited to an eater that he eat thereof, except it be carrion, or blood poured forth, or swine flesh for that verily is foul or the abomination which was immolated to the name of other than Allah. But who so is compelled (thereto), neither craving nor transgressing, (for him) lo ! your Lord is Forgiving, Merciful.
6:119. Eat of that over which the name of Allah Has been mentioned, if you are believers in His revelations.
6:120. How should you not eat of that over which the name of Allah Has been mentioned, when He has explained to you that which is forbidden to you, unless you are compelled thereto. But surely! many are led astray by their own lusts through ignorance. Surely! your Lord, He is best aware of the transgressors.
2:168. O mankind! Eat of that which is lawful and wholesome in the earth, and follow not the footsteps of the Satan. Surely! he is an open enemy for you.
2:169. He enjoineth upon you only the evil and the foul, and that you should tell concerning Allah that which you know not.
2:172. O you who believe! Eat of the good things which We have provided you, and render thanks to Allah if it is (indeed) He whom you worship.
5:4. They ask you (O Muhammad) what is made lawful for them. Say : ( all ) good things are made lawful for you. And those beasts and birds of prey which you have trained as hounds are trained, you teach them that which Allah taught you; so eat of that which they catch for you and mention Allah's name upon it, and observe your duty to Allah. Surely! Allah is swift to take account.
6:143. And of the cattle (He produceth) some for burdens, some for food. Eat of that which Allah Has grant to you, and follow not the footsteps of the Satan, for surely! he is an open enemy to you.
5:88. Eat of that which Allah Has bestowed on you as food lawful and good, and keep your duty to Allah in Whom you are believers.
16:114. So eat of the lawful and good food which Allah Has provided for you, and thank the bounty of your Lord if it is Him you serve.
