"If you release your dog and other dogs over with you have not mentioned the name of Allah join him, then do not eat (what they catch), because you do not know which of them killed it (the game),"
Sunan an-Nasa'i Book 42, Hadith 6
← Previous Hadith "I said: 'O Messenger of Allah, I release my trained dogs and they catch (game) for me; can I eat It? He said: 'When you release your trained dogs and they catch (game) for you, then eat.' I said: 'Even if they kill it.' He said: 'So long as no other dogs have joined them." I said: 'I shoot with the Mirad. And they penetrate (the game).' He said 'If they penetrate it, then eat, but if the broad said strikes it, then do not eat.""

Sunan an-Nasa'i Book 42, Hadith 5 Next Hadith → "I asked the Messenger of Allah about dogs and he said: 'If you release your dog and say the name of Allah, then eat, but if you find another dog with your dog then do not eat, for you only said the name of Allah over your dog, not any other.""
