Allah The Almighty

Let us now try to answer a number of basic questions about the Almighty:

1. How can you describe Him?

Numerous verses of the Holy Qura\'n point out to His existence. Consider the argument of His Friend Ibrahim (Abraham, as) who said: "My Lord is the One Who brings life and Who causes death" (Qura\'n, 2:258), and the argument of Moses who said, "[He is] your Lord and the Lord of your fathers of old" (Qura\'n, 26:26). Also consider these verses:
Our Lord is the One Who gave everything its creation, then He guided it (to its destination). (20:50)The Lord of the East and the West: there is no god but He; therefore, take Him for a protector. (73:9)

2. Can you define Him?

The Exalted One says that He defies definition.. nothing at all is like Him (Qura\'n, 42:11).

3. Can one ask "What is He?"

Pharaoh asked Moses, "And what is the Lord of the worlds?"(Qura\'n, 26:23). Moses answered by saying that He is "Your Lord and the Lord of your fathers of old" (Qura'n, 26:26). There is no way to know Him by defining 'what' He is; rather, one can get to know the proofs of His Existence, Might, Knowledge, Wisdom, Mercy and His being the Creator of everything. "Do not think about Allah" said Imam `Ali, "rather, think about what Allah has created, for thinking about Allah only increases one\'s bewilderment"

Muhammed, the Messenger of Allah, has said, "One among you who knows Allah best is the one who fears Him most, and I fear Him even more than him." Ibn `Abbas [1] says that a bedouin once came to the Messenger of Allah and said, "O Messenger of Allah! Teach me of the most unusual of knowledge!" He asked him, "What have you done with the peak of knowledge so that you now ask about its most unusual things?!" The man asked him, "O Messenger of Allah! What is this peak of knowledge?!" He said, "It is knowing Allah as He deserves to be known." The bedouin then said, "And how can He be known as He ought to be?" The Messenger of Allah answered, "It is that you know Him as having no model, no peer, no antithesis, and that He is One and only: He is the One Who is Apparent yet Hidden, the First and the Last, having no peer nor a similitude; this is the true knowledge about Him."
