"Say We believe in God and what is revealed to us and what was revealed to Abraham and Ishmael and I`saac and Jacob and the Tribes, and what was entrusted to Moses and Jesus and the prophets from their Lord. We make no distinction between any of them and to Him we have surrendered." (Quran 3: 84)

Serve No gods besides the "One God"

And verily We have sent among every nation a Messenger proclaiming Worship Allaah Alone and avoid all false deities. (The Qurán 16:36)

The most important concept of the Islamic system is the Unity of Godhead. This unity of Godhead is called as Tawhid (Oneness of God) in Arabic. It is the backbone of Islam and of all Islamic principles. It is the basis of unification of mankind and the only acceptable way for God for the progress and salvation of human civilization establishing universal principles of dignity, justice and freedom for all.
