Al-Awwal - The First, The Pre-Existing.

Allah سُبْحَٰنَهُۥ وَتَعَٰلَىٰ is Al-Awwal (in Arabic: ٱلأَوَّلُ), He is The One whose existence is without beginning. He is truly the first, and nothing was before Him.

There was nothing before Him, and everything other than Him. He brought into existence from absolutely nothing. Al-Aakhir (the Last): There is nothing after Him and, being Infinite, He will exist for all eternity.

Occurrence: once.

Evidence: “He is the First and the Last, the Outward and the Inward; and He has full knowledge of all things.” (Surah 57 «Al-Hadid» , Ayah 3)
