Thanks for correction.
both conditions should be fulfilled i thought only one was sufficient .
The weapon used for hunting should be able to cut through, like, a knife or a sword, or should be sharp like a spear or an arrow, so that due to its sharpness, it may tear the body of the animal. If an animal is hunted with a trap, or hit by a piece of wood or a stone, it does not become Pak, and it is haraam to eat its meat. And if an animal is hunted with a gun and its bullet is so fast that it pierces into the body of the animal and tears it up, the animal will be Pak and halal, but if the bullet is not fast enough and enters the body of the animal with pressure and kills, or burns its body with its heat, and the animal dies due to that heat, it is a matter of Ishkal to say that the animal is Pak or halal.
The animal will be haraam if the hunter reaches it when it is already dead, or, even if it is alive, he has no time left to slaughter it. And if he has enough time to slaughter it and he does not slaughter it till it dies, it will be haraam.
