Who Is Allah?

Question:
Who is Allah?
Answer:
All perfect praise be to Allah, The Lord of the Worlds. I testify that there is none worthy of worship except Allah, and that Muhammad 
is His slave and Messenger.
Knowing Allah, the Exalted, is the most established form of knowledge, since He is known for every being in the universe; even disbelievers, like Pharaoh, admit His existence in the depths of their hearts although they deny that apparently.
Allah Says (what means): {[Moses] said, "You have already known that none has sent down these [signs] except the Lord of the heavens and the earth as evidence, and indeed I think, O Pharaoh, that you are destroyed.".} [Quran 17:102]
Allah also Says (what means): {And they rejected them, while their [inner] selves were convinced thereof, out of injustice and haughtiness. So, see how was the end of the corrupters.} [Quran 27:14]
Allah Says on the tongue of Pharaoh (what means): {"I believe that there is no deity except that in whom the Children of Israel believe, and I am of the Muslims."} [Quran 10: 90]
While he (Pharaoh) used to say (what means): {…"O eminent ones, I have not known you to have a god other than me. …….} [Quran 28: 38]
For sure, nobody in this universe fails to recognize the existence of Allah since all signs of this universe bear witness to Him.
Pieces of evidence that indicate His existence are of two kinds:
1- The Quran: Allah Says (what means): {Allah witnesses that there is no deity except Him, and [so do] the angels and those of knowledge - [that He is] maintaining [creation] in justice. There is no deity except Him, the Exalted in Might, the Wise..} [Quran 3:18]
2- Contemplating and thinking about His Signs shown in the universe. Allah Says (what means): {Say, [O Muhammad], "Travel through the land and observe how He began creation. Then Allah will produce the final creation. Indeed Allah, over all things, is competent."} [Quran 29:20]
Allah also Says (what means):
{Or were they created by nothing, or were they the creators [of themselves]?} [Quran 52:35]
{Or have they the depositories [containing the provision] of your Lord? Or are they the controllers [of them]?} [Quran 52: 36]
Allah, the Great and Almighty, addresses those who deny His existence:
Deniers! No doubt that you are existent and you cannot deny such a fact, and heavens and earth are existent. It is proved, from intellectual point of view, that there must be a founder for every thing in this universe, and this is known even to the shepherd in the desert who normally says: 'Dung indicates existence of camels; traces show that somebody has been present; a sky with constellations and a ground with mountain passes: Don't they give a proof to the existence of The All-Knowing and The Expert?
Then, deniers do not claim that they created themselves, the earth and heavens. This means that Allah is the originator of all creation from nothing. He, the Exalted is the First and the last, The Everlasting and the Maker of everything, and The Only One who does what He wants.

There are also many cosmic Signs proving Allah’s existence. We have highlighted some of these signs in Fataawa 85461 and 85823; so please refer to them.
Allah knows best.
