Shahada,
that is, the testimony: Laa Ilaaha illallaahu
Muhammadur-Rasullullah, is not merely a formula of faith; it is a
complete commitment that Allah demands from a believer, so that he establishes
only Allah alone in his heart as his Lord, his God, and that he does not
worship any other things, or people, or animals, or claim that these are gods
alongside Allah. This person must be conscious that when he pronounces these
words, that Allah alone is worthy of worship, not others, and NOT EVEN THE
PROPHETS whom Allah sent upon the earth.
That is why Shahada is in two phases: first, to believe in Allah and worship Him alone, and second, to believe in Muhammad (pbuh), His Prophet, His Messenger. Here, what is important to retain is that Allah makes it clear: Beware! I alone am worthy of worship – you must pray to Me alone. My Messenger Muhammad (pbuh), just like all the prophets and messengers before him and even those who will come after him, are only human beings who come from Me to show you the path that will lead you to Me.
