Musannaf Ibn Abi Shaybah 20757 — A dog sent after its game when

Jamil bin Zayd (may Allah have mercy on him) said: I asked Sayyiduna Ibn Umar (may Allah be pleased with them both) about the game of dogs. He said: Are they not collared? I said: Of course! I set out leading them. He said: Do you lead all of them? I said: Some of them I lead, and some of them follow me. Sayyiduna Ibn Umar (may Allah be pleased with them both) said: When you see game, release your dog and mention the name of Allah, then eat whatever it catches. As for the dog that follows you, if it catches the game, have nothing to do with it, unless you find it alive and slaughter it. And if a dog that you did not send mauls it and kills it, that is forbidden.
