I heard Sayyiduna Abdullah bin al-Zubayr (may Allah be pleased with them both) say: The Prophet (peace and blessings be upon him) recited the tashahhud (in the prayer): "In the name of Allah and by Allah, the best of names. All reverence, all good things and all prayers are for Allah. I bear witness that there is none worthy of worship except Allah, He is alone, and I bear witness that Muhammad (peace and blessings be upon him) is His servant and Messenger; He sent him with the truth as a bearer of glad tidings and a warner, and that the Hour is coming, there is no doubt about it. Peace be upon you, O Prophet, and the mercy of Allah. Peace be upon us and upon the righteous servants of Allah. O Allah, forgive me and guide me."
This tashahhud was (recited) in the first two rak'ahs.
