Sayyiduna Abdullah bin Amr (may Allah be pleased with him) narrates: The Prophet (peace and blessings be upon him) came to pray Zuhr and found a she-camel tied up. He asked: "Where is the owner of this mount?" No one answered him. The Prophet (peace and blessings be upon him) went inside the mosque and prayed, and when he had finished the prayer he found the she-camel tied up just as before. He asked: "Where is the owner of this mount?" Then that man answered him; the man said: "It is I, O Prophet of Allah." The Prophet (peace and blessings be upon him) said: "Do you not fear Allah Almighty concerning her? Either keep her hobbled, or let her go so that she may seek (her food) for herself."
Al-Tabarani recorded it, and its chain is jayyid (good).
