A muslim who does not believe in any of God's commandments has a defective faith. This includes all the essentials of faith.
I need an answer. If I do not believe in MGA being the promised messiah, do I still remain a Muslim? If believing in MGA as being the promised messiah is an essential of faith and I rebel this notion, it should make me a non-muslim, right? Specially, going through the website, it is abundantly clear that this 'essential' is one of the most important one for a 'muslim'.
There is no such thing as 'incomplete Muslim'.
