Abu Nu'aym (may Allah have mercy on him) said: Qadi Shurayh (may Allah have mercy on him) came out from Ziyad, and a man met him and said: Your age has advanced, your bones have grown frail, and your son has taken bribes. He went back to Ziyad and informed him of this. He said: Who told you this? He said: I do not know him, so excuse me (from the office). Ziyad said: I will not excuse you until you point me to a man. So he pointed to Abu Burdah (may Allah have mercy on him), and he made him judge.
