Hadith.2726 - Ibn Muskan narrated from Abu Basir, who said
I asked Abu Abdullah (as) about a man in the state of ihram who shot at game, breaking its leg or hand, and it ran off so that he did not know what happened to it.
Imam (as) said: "He must pay its full expiation."
I asked: "What if he later sees it grazing and walking?"
Imam (as) said: "He must pay a quarter of its value."
