He who frees his servants from all danger and obstruction.
“He is Allah, than whom there is no other God, the Sovereign Lord, The Holy One, PEACE, The Keeper Of Faith, the Guardian, the Majestic, the Compeller, the Superb. Glorified be Allah from all that they ascribe as partner (unto Him).”
(59:23) The Holy Quran
