Hazrat Abdullah bin Mas'ud (may Allah be pleased with him) narrates that the Messenger of Allah (peace and blessings be upon him) taught me the Tashahhud while my hand was in the hand of the Messenger of Allah (peace and blessings be upon him). He taught me the words of Tashahhud just as he would teach us a surah from the Holy Qur'an. The words were as follows: All verbal worship, physical worship, and financial worship are for Allah. O Prophet, peace be upon you, and the mercy and blessings of Allah be upon you. Peace be upon us and upon the righteous servants of Allah. I bear witness that there is no deity except Allah, and I bear witness that Muhammad (peace and blessings be upon him) is the servant of Allah and His Messenger. These were the words as long as the Messenger of Allah (peace and blessings be upon him) was in this world. When he passed away, instead of saying "As-salamu 'alayka ayyuhan-nabiyyu," we used to say "As-salamu 'ala an-nabiyyi."
