1-everlasting Allah He has always existed and always will exist.

2-He has no beginning and he has no end. He is eternal.

3-He always has existed and He never was created, as He is not like His creation, nor similar to it, in any way.

The concept of God is summarized in the Quran as:

I seek refuge with Allah from the accursed satan

📖 { “Say, He is God, the One. God, the Absolute. He does not give birth, nor was He born, and there is nothing like Him.”} (Quran 112:1-4)
