Zaid bin Aslam narrates from his father that he set out towards the land of Shaam with Sayyiduna Umar bin Khattab (may Allah be pleased with him). He says: Then I heard Sayyiduna Abu Ubaidah bin Jarrah (may Allah be pleased with him) saying that I heard the Messenger of Allah (peace and blessings be upon him) say: "Do not abuse the ruler, for he is Allah's shade on His earth."
