6:145Al-An'aam

The people of pre-Islamic times used to eat some things and leave others alone, considering them unclean. Then Allah sent His Prophet (ﷺ) and sent down His Book, marking some things lawful and others unlawful; so what He made lawful is lawful, what he made unlawful is unlawful, and what he said nothing about is allowable. And he recited: "Say: I find not in the message received by me by inspiration any (meat) forbidden to be eaten by one who wishes to eat it...." up to the end of the verse.

from Ibn 'Abbas: "A man came to the Prophet (ﷺ) and said: 'O Messenger of Allah! When I consume meat and I get around women, my desires get the best of me. So I made meat unlawful for myself.' So Allah revealed: O you who believe! Make not unlawful the good things which Allah has made lawful to you, and transgress not. Verily Allah does not like the transgressors. And eat of the things which Allah has provided for you, lawful and good (5:87-88)."

"When (the following) was revealed: Those who believe and do righteous good deeds, there is no sin on them for what they ate, if they have Taqwa and perform good (5:93). The Messenger of Allah (ﷺ) said to me: 'You are among them.'"

I came to Allah's Messenger (ﷺ) and said, "O Allah's Messenger (ﷺ)! We are living in the land of the people of the Scripture and we take our meals in their utensils, and in the land there is game and I hunt with my bow and trained or untrained hounds; please tell me what is lawful for us of that." He said, "As for your saying that you are living in the land of the people of the Scripture and that you eat in their utensils, if you can get utensils other than theirs, do not eat in their utensils, but if you do not find (other than theirs), then wash their utensils and eat in them. As for your saying that you are in the land of game, if you hung something with your bow, and have mentioned Allah's Name while hunting, then you can eat (the game). And if you hunt something with your trained hound, and have mentioned Allah's Name on sending it for hunting then you can eat (the game). But if you hunt something with your untrained hound and you were able to slaughter it before its death, you can eat of it."

"I said: 'O Messenger of Allah, we live in a land where people hunt, and I hunt with my bow and with my trained dog, and with trained dog, and with my dog which ins not trained.' He said: 'whatever you catch with your bow, mention the name of Allah over it and eat. Whatever you catch with the trained dog, mention the name of Allah over it and eat. Whatever you catch with your untrained dog and you reach it while it is still alive, then slaughter it, and eat.""( Sahih
