Musannaf Ibn Abi Shaybah

Hazrat Tamim bin Tarfa narrates that two persons brought a dispute over a camel to the service of the Prophet (peace and blessings be upon him). Then each of them brought two witnesses to the Prophet (peace and blessings be upon him), and both sets of witnesses testified in favor of their respective claimants that the camel belonged to them. So the Prophet (peace and blessings be upon him) decided the matter of the camel in favor of both of them.
