Musannaf Ibn Abi Shaybah

It is narrated from Hazrat Ammarah that two men testified before Qazi Shurayh regarding a certain matter about a person. A’mash says that I think the testimony was about a donkey. The witnesses said, “We testify that he bought this donkey from so-and-so.” Then one of the witnesses said, “I testify that this person is a wicked man.” Shurayh said, “How do you know that he is wicked? Stand up, your testimony is not accepted.”
