If a person says BISMILLAH HIRREHMAA NIRRAHEEM and throws a knife or any other tool at an animal in order to hunt it and eat it, then after catching the animal if it is still alive does the person have to slaughter it or he can just wait for the animal to die . Please give all the necessary ahkaam of hunting (like if somebody did not say tasmia, or can he say BISMILLAH ALLAHU AHAD instead of BISMILLAH ALLAHU AKBAR, or is it OK to hunt with a gun, etc,.).
