وَمَآ أَرْسَلْنَا مِن قَبْلِكَ مِن رَّسُولٍ إِلَّا نُوحِىٓ إِلَيْهِ أَنَّهُۥ لَآ إِلَٰهَ إِلَّآ أَنَا۠ فَٱعْبُدُونِ
Commentary:
The verse gives a third argument in favour of the Unity of God. It purports to say that all the Divine Messengers and great religious reformers who appeared among different nations and countries at different times testified with one voice to the Oneness of God which was their common mission. In spite of the fact that with the passage of time the teachings of these Prophets became tampered with and were subjected to distortions and interpolations, the belief in the Unity of God continued to be the basic principle of all these teachings. These Prophets and Messengers appeared among all nations and peoples and the greatest of all, the Holy Prophet Muhammad, appeared at a time when the whole world was immersed in the Cimmerian darkness of moral turpitude, and idol worship was rife among every people and country in one form or another and was practised in its most heinous form in Arabia where the Holy Prophet preached his message of the Oneness of God. He carried on such an effective and relentless campaign against idolatry that it disappeared from Arabia never to return. Not only did he condemn and forbid idol-worship and enjoin and impress upon his people the worship of One True God but also gave unanswerable arguments in support of monotheism and against polytheism and he fully succeeded in engendering in the minds of his followers an invincible faith in Divine Unity and an equally implacable hatred for shirk—setting up equals with God. In four short sentences of one of its shortest Surah—Al-Ikhlas, the Quran has refuted and demolished in a most beautiful and effective manner four forms of polytheism. The first verse proclaims the absolute Unity of God. It says: "Say, He is Allah, the One." It means that out of ignorance and perversity man invents and indulges in most fantastic theories and ideas about God. But the central and pivotal fact about the Divine Being remains that He is absolutely One in every respect and manner. He is neither the beginning nor the end of anything and He is not like anything, nor any thing is like Him. To regard anything like Him is to impugn His absolute Unity.
In the words, "Allah, the Independent and Besought of all," the Quran has demolished the second kind of shirk i.e. to ascribe Divine powers and attributes to other beings and things. The verse says that God has need of nobody but all beings and things have need of Him. It is therefore foolish and futile to have recourse to beings and things which themselves are wholly dependent upon God. The third verse, viz. "He begets not, nor is He begotten" refutes and repudiates the third kind of polytheism i.e. the doctrine of God being the father or son of anybody. The verse means to say that God is eternal and everlasting. He has begotten no son who should take His place, nor is He begotten of anyone from whom He should have inherited His Divine powers and attributes. He was always Independent and Besought of all and will ever be so. So we should worship Him and call on Him alone for the fulfilment of our needs and requirements. The verse "And there is none like unto Him," exposes the folly and futility of the fourth kind of shirk. It signifies that it is beyond any created thing to be His partner in Divinity i.e. to be like Him in His person or attributes. God is far exalted and above that to which man can aspire. However high man may rise, he cannot even touch the fringes of the precincts of Divinity and will ever remain God’s servant.
This is the most sublime conception of absolute Unity of God as taught and inculcated by the Quran.
At another place (2:256) the Quran has shed further light on Divine Unity. It says: "There is no God but Allah, the Living, the Self-Subsisting and All-Sustaining. Slumber seizes Him not, nor sleep (i.e. no interruption ever takes place in His works). To Him belongs whatsoever is in the heavens and whatsoever is in the earth. Who is he that will intercede with Him except by His permission (i.e. God grants the prayers of His servants but no one should think that He can compel God to accept His prayer. It is after He has granted the permission to any of His servants that he can intercede with Him)? He knows what is before them and what is behind them (i.e. He knows the past and the future. His knowledge is complete and all-comprehensive because full control is not possible without complete knowledge and complete knowledge is the never-failing accompaniment of absolute Unity). And they encompass nothing of His knowledge except what He pleases (i.e. man can accomplish nothing except with the help of the knowledge that he receives from God). His knowledge extends over the heavens and the earth (i.e. not an atom moves in the heavens and the earth without His permission and every particle is subject to His control). And the care of them burdens Him not (i.e. the universe will continue to exist and function under the never-failing supervision and protection of God). And He is the High (i.e. every atom of the universe bears witness to His Almightiness and He is so exalted that human reason cannot attain to full comprehension of Him); and yet He is great (i.e. He is so manifest in His great works that every honest seeker after Him can attain to communion with Him)." This is the very high and noble conception of Divine Unity which the Holy Prophet gave to the world and for which he worked and suffered. He told the people of the world that Divine Unity consists in the fact that man should rise to such a high stage of spiritual exaltation as to become completely engrossed in One God and become at one with Him. It is when man reaches this high stage of moral and spiritual development that he can be said to have attained the great object of his creation.
