It is narrated from Sayyiduna Abu Musa al-Ash'ari (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) passed by a young lamb (that had been thrown away) and said: "Do you think that this became worthless in the eyes of its owners when they threw it away?" The Companions (may Allah be pleased with them) said: "Yes, by Allah, O Messenger of Allah!" He (peace and blessings be upon him) said: "The world is more worthless to Allah than this lamb was to its owners when they threw it away."
Imam al-Tabarani (may Allah have mercy on him) said: "This hadith is narrated from Abu Musa (may Allah be pleased with him) only with this chain; Wahb bin Yahya bin Zimam is alone in narrating it."
