i have a close friend who just reverted to islam a couple of months ago and already she is learning namaz. so i was looking at the prayers and i came across this:
"O' Allah! You alone deserve all veneration, worship and glory. O'Prophet! Peace be on you and the mercy of Allah and His blessings. Peace be upon us and on virtuous servants of Allah. I bear witness that none is worthy of worship save Allah and I bear witness that Muhammad (peace be upon him) is His chosen servant and His Messenger."

so couldn't ya rasool allah simply be a poetic way of speaking? even in the above, it is obvious that the person praying is not confused as to who alone gets the worship?
