He who loves, helps, protects, safeguards, guides, blesses and rewards all His righteous servants and be- comes a friend of them.
“ALLAH IS THE PROTECTOR OF THOSE WHO
HAVE FAITH: from the depths of darkness He will lead them forth into light. Of those who reject faith the
patrons are the Evil Ones: from light they will lead them forth into the depths of darkness. They will be Compan- ions of the Fire, to dwell therein (forever).”
(2:257) The Holy Quran

From the root w-l-y with classical Arabic connotations: to be near, close, nearby to be a friend, helper, supporter to defend, guard (lit. friendly dealing) to be in charge, to turn one toward something to be the master, owner, lord.
Allah is lover, protector and lord. He is lovingly supportive.
He is the protecting friend. He guards and rules all of creation.
He lovingly guides mankind to turn toward the path of righteousness.
