Allaah 
is the proper name applied to the true God who exists necessarily
by Himself comprising all the excellent Divine names and attributes of
perfection. Allaah is One and Unique. He has no son, no partner, nor equal.
He is the sole Creator and Sustainer of the universe. Every creature bears
witness to His Oneness, Divinity, and Ruboobiyyah [Ruboobiyyah, inf. of
Rubb], and to the uniqueness of His attributes and names.
His essence does not resemble the essences. He does not inhere in anything,
nor does anything inhere in Him. "There is none like unto Him." He is the One,
the Sole, the Indivisible. He is the Rubb [Some translate the term 'Rubb'
into 'Lord', the meaning of 'Rubb' is far more comprehensive than to be
restricted to a single word such as 'Lord'. Rubb, means, among other things,
the Creator, the Sustainer, the Provider, and the One in whose hands is the
disposal of all affairs], who accomplishes all affairs, Allaah is the
Omnipotent and the Omniscient.
His knowledge comprehends in perfect manner all things, hidden or
manifest. He is greater than can be encompassed by the knowledge of His
creatures. He knows everything, and He is aware of all that takes place
in the earth and the heavens. Allaah , the Supreme, is the Rubb of everything
and has a free hand in disposal of all affairs. His mercy encompasses
everything. He is far removed from injustice or tyranny. He is wise in all
His actions, just in all His decrees. His justice ensures order in the
universe in which nothing is out of order.
There is no one to share His dominion, nor does He take an aide or supporter
from His creatures. He is nearer to man than man's own jugular
vein [TNQ 50:16].
Whenever a believer is in need or distress calls on Him, He responds.
Allaah has revealed His final Scripture, the Qur'aan, to that last of
His Messengers, Muhammed 
who was responsible for conveying the Message
of Islam to mankind. He is the Exalted Allaah . Glory is due to Him.
