What you are saying here is very problematic and you are committing shirk here. By saying Muhammad is the embodiment of the Holy Quran are you saying Muhammad is the word of Allah? Is Muhammad the word of Allah made flesh?

Secondly if Muhammad is the embodiment of the Holy Quran how come Allah had to forgive him for his past and future sins in Surah 48:2? Why do the Hadith record him asking forgiveness for sin if he obeyed all the rules set by Allah?

Third, so Muhammad obeyed Allah by having sex with a nine year old Aisha? And ordering rape of female captives from war? You admit these are all worship to Allah?

Finally by repeating the shahada you have just proved again Islam is worship of Muhammad as well as Allah. Why does one have to believe in Muhammad as a prophet as well as Allah as God? What true prophet in human history has said people should believe in him alongside God?
