It is narrated from Sayyiduna Ibn Abbas (may Allah be pleased with them both) that when the Prophet (peace and blessings be upon him) finished the prayer he would say: "There is no true god except Allah, alone, without partner. His is the dominion and His is all praise; He gives life and causes death, and He has power over all things. O Allah, none can withhold what You give, and none can give what You withhold, and the status of a man of status cannot avail him anything against You."
