Warrad, who was the secretary of Sayyiduna Mughirah (may Allah be pleased with him), narrates: Sayyiduna Mughirah bin Shu'bah (may Allah be pleased with him) wrote in a letter to Sayyiduna Mu'awiyah (may Allah be pleased with him): When the Prophet Muhammad (peace and blessings be upon him) completed the prayer and said salam, he used to recite: "There is no deity except Allah, He is One, He has no partner. Sovereignty belongs to Him, and all praise is for Him, and He has power over everything. O Allah! No one can withhold what You give, and no one can give what You withhold, and the status of any person of status is of no benefit against Your will." This narration is also transmitted with another chain from Sayyiduna Mughirah (may Allah be pleased with him) from the Prophet Muhammad (peace and blessings be upon him) in a similar manner.
