Quran 5:3-5
Yes it is Halal.
Yes I know I have quoted the ayah above. I think in this ayah hunted mean only killed by your trained animal alone . @faisalharoon can you please get me the answer to my query.? JazakAllah
If the blood is drained while killing the bird with bullet than the batair becomes halal. Also before firing the shot Bismillah is necessary and the person firing the shot must believe in tawheed. If the blood does not drains out than the animal is impure and forbidden to eat. The tranquillizer gun makes the bird unconscious. I dont know if the blood is drained in this case. if it does than its halal.
