Allah is the Self-SUBSISTING Whose Existence does not need anything; He is Self-Existing and Self-Sufficient; everybody dependson Him. It is He Who gives existence to every existing thing; He dispenses with everybody and everything, but no one can dispense with Him. He istoo exalted to be limited to locations and is far above change; what befalls souls can never befall Him; He is Supreme in perfection and in organizing His Kingdom. This name, the Self-SUBSISTING, is never attributed to anyone save to Him.
Allah is the Ever-Living, the Self-SUBSISTING; He says, “All faces shall be humbled before Him, the Living, the Self-Subsisting, Eternal.” (TA-HA, 111), where this will be on Doomsday, “God! There is no god but He, the Living, the Self-Subsisting, Eternal” (BAQARA, 255). That is to say, He is the Ever-Living, the Self-SUBSISTING eternally and permanently.
It was said that this name is Allah’s greatest Attribute, and that if someone calls for His Help by calling upon this name, Allah will succour him. Prophet Muhammad, Allah's blessings and peace be upon him, said, ‘O the Ever-Living, the SELF-SUBSISTING! I’m calling for Your Mercy’s relief!’ (HADITH).
Glory be to the Self-SUBSISTING, Praise and Glory be to Him, He is Allah.
