Sayyiduna Anas (may Allah be pleased with him) narrates: The Prophet (peace and blessings be upon him) passed by a dead goat, and he (peace and blessings be upon him) said: "The world is more worthless to Allah Almighty than this (that is, the goat) is to its owners."
Al-Bazzar recorded it, and its narrators have been declared trustworthy.
