Why must there be a God?

The question of why there must be a God is deeply rooted in philosophical and theological considerations. The Qur'an presents several arguments that point to the necessity of God's existence, emphasizing His unique attributes and the signs of His creation.

In Surah Aal-i-Imraan, it is stated, Allah! There is no god save Him, the Alive, the Eternal. 3:2. This verse underscores the uniqueness of God as the singular source of life and existence, suggesting that everything else is contingent upon Him. The concept of God's eternal nature implies that there is a foundational being whose existence does not depend on anything else, which is a core argument in favor of the necessity of God.

Furthermore, in Surah Al-Muminoon, the Qur'an states, Allah hath not chosen any son, nor is there any god along with Him; else would each god have assuredly championed that which he created, and some of them would assuredly have overcome others. 23:91. This verse argues against the existence of multiple gods, asserting that the presence of multiple deities would lead to chaos and conflict in creation. The harmony and order observed in the universe suggest a singular, all-powerful Creator who establishes and maintains this order.

Additionally, the Qur'an warns against invoking other gods alongside Allah, stating, Therefor invoke not with Allah another god, lest thou be one of the doomed. 26:213. This highlights the importance of monotheism and the belief that God alone possesses the power to create and govern the universe. The logical conclusion is that the existence of God is necessary to explain the origin and sustenance of all creation.

The teachings of the Prophet Muhammad ﷺ also support this understanding. In various narrations, he emphasized the need to recognize the singularity of God and His role as the Creator. The Prophet ﷺ corrected expressions that implied sharing divine will with others, teaching that believers should affirm God's exclusive sovereignty.

In summary, the necessity of God is illustrated in the Qur'an through arguments of His unique existence, the order of creation, and the implications of monotheism, supported by the teachings of the Prophet ﷺ. These points collectively reinforce the belief that there must be a God who is the ultimate source of all that exists.
