أَللهَ

The name أَللهَ “Allah” is derived from the Arabic root word “Ilah” (إله), which means “god” or “deity.” “Ilah” is a general term that refers to a god, divinity, or object of worship. However, “Allah” is a unique and specific term that denotes the one and only object of worship “God.”

ٱللَّهُ لَآ إِلَـٰهَ إِلَّا هُوَ ٱلۡحَىُّ ٱلۡقَيُّومُ‌

“Allah! there is no God but Him  (none has the right to be worshipped but Him), the Living, the Self-subsisting, Eternal,”

Quran 2:255

The name “Allah” is used in the Qur’an throughout its verses, and it signifies not just a god but the only God who is the source of all creation. Allah is understood as being omnipotent, omniscient, merciful, just, and beyond human comprehension. The name “Allah” represents the totality of God’s essence and attributes, and it is used in various forms of worship and prayer in Islam, most notably in the Shahada (declaration of faith) and during the daily prayers.

Allah is beyond any form, shape, or concept that humans may imagine. In Islam, Allah is not confined to a particular time or space, nor is He comparable to any of His creations. The name “Allah” expresses His transcendence and immanence, meaning that He is both beyond human understanding and intimately close to all of creation.
