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.
