Sayyiduna Abdullah bin Mas'ud (may Allah be pleased with him) says: The Prophet (peace and blessings of Allah be upon him) taught him the Tashahhud: "All greetings, prayers, and good things are for Allah. Peace be upon you, O Prophet, and the mercy of Allah and His blessings. Peace be upon us and upon the righteous servants of Allah. I bear witness that there is no god but Allah, and I bear witness that Muhammad is His servant and Messenger."
