Sayyiduna Abdullah bin Umar (may Allah be pleased with them both) narrates: The Prophet (peace and blessings be upon him) used to recite in Tashahhud:“All verbal and physical acts of worship are exclusively for Allah. O Prophet! Peace be upon you and may Allah’s mercy descend upon you.”Sayyiduna Abdullah bin Umar (may Allah be pleased with them both) says: I have added these words: and may His blessings also descend (the words of the Prophet’s Tashahhud are) Peace be upon us and upon all the righteous servants of Allah. I bear witness that there is no deity except Allah. Sayyiduna Abdullah bin Umar (may Allah be pleased with them both) says: I add these words: He is One, He has no partner (the words of the Prophet’s Tashahhud are) I bear witness that Muhammad (peace and blessings be upon him) is His servant and His Messenger. The chain of this narration is authentic; some narrators have transmitted it as a marfu‘ (attributed to the Prophet) narration, while others have transmitted it as a mawquf (attributed to the Companion) narration.
