Who is Allah?

“Say: He is Allah, the One!
Allah, the Eternal, and Absolute
He begetteth not nor was begotten.
And there is none comparable unto Him (chapter 112)

Allah it is who appointed for you the earth for a dwelling-place and the sky for a canopy, and fashioned you and perfected your shapes, and hath provided you with good things. Such is Allah, your Lord. Then blessed be Allah, the Lord of the Worlds!
He is the Living One. There is no God save Him. So pray unto Him, making religion pure for Him (only). Praise be to Allah, the Lord of the Worlds (chapter 40)

His is the Sovereignty of the heavens and the earth; He gives life and He causes death; and He is Able to do all things.
He is the First and the Last, and the Outward and the Inward; and He is Knower of all things. He it is who created the heavens and the earth in six Days; then He mounted the Throne. He knows what enters within the earth and what comes forth out of it, what comes down from heaven and what mounts up to it. And He is with you whosesoever you may be. And Allah is Seer of what ye do.

His is the Sovereignty of the heavens and the earth and unto Allah (all) things are brought back. He causes the night to pass into the day, and He causes the day to pass into the night, and He is knower of all that is in the breasts (chapter 57).

It is He Who has spread out the earth for (His) creatures. Therein are fruit and date-palms, producing spathes (enclosing dates); also corn, with (its) leaves and stalk for fodder, and sweet-smelling plants. He created man from sounding clay like unto pottery, And He created Jinns from fire free of smoke (chapter 55).

He is Allah, than whom there is no other God, the Knower of the Invisible and the Visible. He is the Beneficent, Merciful. 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, and the Superb. Glorified be Allah from all that they ascribe as partner (unto Him). He is Allah, the Creator, the Shaper out of naught, the Fashioner. His are the most beautiful names. All that is in the heavens and the earth glorified Him, and He is the Mighty, the Wise (chapter 59).

He has created the heavens and the earth for just ends: Far is He above having the partners they ascribe to Him! He has created man from a sperm-drop; and behold this same (man) becomes an open disputer. And the cattle He has created for you, whence you have warm clothing and uses, and whereof you eat. It is He who sends down rain from the sky: from it you drink, and out of it (grows) the vegetation on which you feed your cattle. With it He produces for you corn, olives, date-palms, grapes and every kind of fruit: verily in this is a sign for those who give thought. He has made subject to you the Night and the Day; the sun and the moon; and the stars are in subjection by His Command: verily in this are Signs for men who are wise”.
