Al-Awwal
He is the One before Whom there was nothing. All creatures came into existence by His creation. As for Him, there is no beginning for His existence.
The names ‘the First’ and ‘the Last’ occur in the verse that says, {He is the First and the Last, and the Manifest and the Hidden and He is All-Knowing of everything.} [Sūrat Al-Hadīd: 3]
It also occurs in the Prophet’s Sunnah in a Hadīth reported by Abu Hurayrah (may Allah be pleased with him) involving a supplication to be said before sleep, “O Allah, You are the First and there is nothing before You. You are the Last and there is nothing after You.”[1] In light of this great name, I would say:
This gives you a sense of tranquility and trust in His promise.
