Comparative religion - Are we not part of God?

Adaab This interesting question of whether a person can be called God , gave rise to another question in my mind. I have read many times at past that God is one. But I have read an alternative view that some religions consider God exists everywhere, and within every creatures. In other words, every creature is a part of God. So what is the Islamic view on this? So far I know that a person can be never considered as a separate God, but can everybody equally be revered as part of God?
