Sayyiduna Abu Sallam al-Sulami (may Allah be pleased with him) said that the Messenger of Allah (peace and blessings be upon him) said: "Soon there will be rulers over you who will own your necks. They will speak to you and lie to you, and they will act and act badly. They will not be pleased with you until you call their evil good and affirm their lies. So give them their due as long as they are content with it."
