Al-Awwal (ES)
Allah is Al-Awwal, He is The One whose existence is without beginning. He is truly the first and nothing was before Him.
From the root a-w-l which has the following classical Arabic connotations: to be first, principle, to be before to come back to, to return to precede, to be the first part to be foremost
He is the First and the Last, the Ascendant and the Intimate, and He is, of all things, Knowing. (Quran 57:3)
And they urge you to hasten the punishment. But Allah will never fail in His promise. And indeed, a day with your Lord is like a thousand years of those which you count. (Quran 22:47)
