Musannaf Ibn Abi Shaybah

A dispute regarding a slave girl who had the disease of debilah was brought before Hazrat Dahhak. This is a well-known disease that does not occur suddenly, so Hazrat Dahhak ruled against the seller. Hazrat Sufyan says that Hazrat Dahhak’s statement is more preferable to me than the statement of Hazrat Shurayh, that when it is known that it is not new, then it will be returned, and an oath will be taken from the buyer that he had not seen it before purchasing, and after seeing it, he is not satisfied with it.
