Silsilat al-Ahadith al-Sahihah

The companion of the Messenger, Sayyiduna Mundhir (may Allah be pleased with him), who was in Africa, narrates that I heard the Messenger of Allah (peace and blessings be upon him) say: "Whoever recites this supplication in the morning: I am pleased with Allah as my Lord, with Islam as my religion, and with Muhammad (peace and blessings be upon him) as my Messenger, then I (Muhammad) guarantee and take responsibility that I will hold his hand until I admit him into Paradise."
