Yahya related to me from Malik from Rabia ibn Abi Abd ar-Rahman
that az-Zubayr ibn al-Awwam came across a man who had taken hold of a
thief and was intending to take him to the Sultan. Az-Zubayr ibn al-
Awwam interceded for him to let him go. He said, "No. Not until I take
him to the Sultan." Az-Zubayr said, "When you reach the Sultan with
him, Allah curses the one who intercedes and the one who accepts the
intercession."
