Have those who disbelieved not considered that the heavens and the earth were a joined entity, and We separated them and made from water every living thing? Then will they not believe?
(The Noble Qu'ran V.21:30)
One GOD Only - He is not the father of anything, not the son of anything, not like anything and nothing compares to HIM.
Below is a Description of The Lord of the Worlds:
In the name of GOD - Most gracious, Most Merciful
Say, He is ALLAH, [the] One,.
ALLAH, The Self-Sufficient Master.
He begets not nor is He begotten,.
And there is none comparable unto Him.
(The Noble Qu'ran V.112:1-4)
Absolute Monotheism - The Only ONE that deserves worship. There is no GOD but HIM.
