A man who abandons his riding animal and another man takes it

It is narrated from al-Sha'bi (may Allah have mercy on him) that the Prophet (peace and blessings be upon him) said: "Whoever finds an animal in a place of destruction, it belongs to the one who catches it and revives it (raises it)."

Al-Hasan (may Allah have mercy on him) said: "If a man leaves his animal in a land without water or pasture, then it belongs to the one who raises it and feeds it fodder and the like."

It is narrated from Amir that a man released his animal and another man took it. Then its owner came and brought the dispute to Amir. Amir said: "This is a matter that was decided before today. If he released his animal in a place of fear and wilderness, then he has more right to his animal; but if he released it in a place of pasture and safety, then he has no right to it."
