Urwah bin al-Zubayr (may Allah have mercy on him) said: I came to Sayyiduna Ibn Umar (may Allah be pleased with them both) and said: O Abu Abd al-Rahman! We sit with the rulers, and they say things about which we know that the truth is otherwise, yet we affirm them; and they give unjust judgements, and we strengthen them in it and make it look good for them. So what is your view on that? He said: "O my nephew, with the Messenger of Allah (peace and blessings be upon him) we used to count this as hypocrisy."
