Musannaf Ibn Abi Shaybah

Hazrat Sha’bi (may Allah have mercy on him) was asked about a case where a person’s wealth was owed by another. He presented two witnesses. Then he wanted to have judgment passed by one of the two witnesses. After that, another person came who had one witness with him. He said to Hazrat Shurayh (may Allah have mercy on him): “Bear witness in my favor.” Hazrat Shurayh (may Allah have mercy on him) replied: “Call the Amir so that I may bear witness (meaning, then I will not be the judge or the decision-maker).”
