GOD, by definition, is
the only Sovereign, Self-Existing, non-created Being to whom everything else
owes its existence and completely depends on for survival and power.
GOD needs nothing to exist, to give Him power,
or to make Him complete. God is entirely Self-Sufficient, Independent, and
Perfect. All attributes of perfection and glory belong to Him; they are
permanent and inseparable from His Being and Essence. They are essential and
inherent characteristics of His very Nature. If He was created, limited,
changeable, needy, or imperfect in any way, He would lose one of His essential
divine attributes and would no longer be God. The definition of God prohibits this.
GOD has always existed and will always exist.
He is not bound by time, space, or the laws of nature, since He cannot be
subject to what He created. Rather, He is beyond them, just as a craftsman is
beyond the dimensions of his own creation.
GOD is incomparable to any of His creations.
The Qur’an clearly says, “There is nothing like Him.” (42: 11) Having a wife,
child, partner, or equal is applicable and appropriate only to creatures. God
does not incarnate at all and should never be depicted. He sends messengers or
prophets with the divine message.
GOD alone gives life, causes death, and has
power over all things; only God should be worshipped (directly, without any
intermediary). 
ALLAH is the all-comprehensive name of the
One, True, Universal God and can never be used to designate any other being. It
is absolutely unique to the Creator of existence. In Arabic, it means ‘the One
exclusively worthy of deification and worship. The most concise yet adequate
definition of God in Islam is given in the Chapter of Ikhlas 112: 1-4: “Say: He
is Allah, the One God, the Self-Sufficient Master. He does not beget nor is He
begotten, and nothing is equal or comparable to Him.”
