The World Federation One Stop Fiqh

Ruling 2627

If the person who sent the dog reaches the prey when there is enough time for him to slaughter it, then in the event that some time passes while he does some things that are preliminary to slaughtering it, such as taking out his knife, and the prey dies, it is lawful to eat it. However, if he does not have anything with him with which to slaughter the prey and it dies, then based on obligatory precaution it is not lawful to eat it. Of course, if in this situation he lets the prey go so that the dog kills it, it becomes lawful to eat.
