Al Qawiy – The Almighty

The possessor of all strength. He who is all-powerful and all powers originate from Him
“We sent aforetime Our Messengers with Clear Signs and sent down with them the Book and the Bal- ance (of Right and Wrong), that men may stand forth in justice; and We sent down Iron, in which is (material for) mighty war, as well as many benefits for mankind, that Allah may test who it is that will help, unseen, Him and His Messengers: for ALLAH IS FULL OF STRENGTH, Exalted in Might (and able to enforce
His Will).”
(57:25) The Holy Quran
From the root
q-w-y with the 
classical Arabic
connotations:
to be strong,
vigorous, potent
to be robust,
hardy, sturdy
to have
sufficient
strength or power
to prevail over.
Allah is supreme in strength. He possesses unlimited endurance.
His vigor and strength prevail over all of creation.
He is beyond all weakness. His strength is inexhaustible.

“He is strong; and inasmuch
as He has intense power” Ghazali
