The answer to the question to anything that Muslims do, always is: Muhammad did it. Islam is a primitive system of religion that is based upon submission -not theology. Muhammad means “the highly praised one.” If Muhammad is the highly praised one, then every Muslim should follow what Muhammad did. Islam is a simple, primitive religion that takes no deep understanding of God. Just do what Muhammad did with blind passion, and you will be considered the most faithful of followers. Muslim means “one who submits to Allah.” Therefore, the one who submits to what Muhammad did (perfect submission to Allah) is the true Muslim.
