God’s Messenger used to teach us the tashahhud just as he would teach us a sura of the Qur’an, and would say, “The blessed adorations of the tongue, acts of worship and all good things are due to God. Peace be upon you, O Prophet, and God’s mercy and blessings. Peace be upon us and upon God’s upright servants. I testify that there is no god but God, and I testify that Muhammad is God’s Messenger.’’ Muslim transmitted it. In the two Sahihs and in al-Jam' bain as-Sahihain I did not find “Peace be upon you” and “Peace be upon us” without the definite article, but the author of al-Jami' transmitted it that way from Tirmidhi.
