Among the evidence bearing witness to the Oneness of Allah (Glorious & Exalted):
Intuitive Evidence
A. By his pure, good nature, man believes in His God Who created him, and that the One Who created him and all things is One God, in accordance with the statement of Allah'sMessenger ﷺ, Every baby is born with a pure, good nature, then his parents turn him into a
Jew, a Christian, or a Zoroastrian. [Sahih al-Bukhari] If something happens suddenly to a person, and it is dangerous to him, or he experiences a tragedy, his tongue automatically says, "Oh God!" or "Oh Lord!" This proves that instinctively, he knows that God, the Creator, is One God, without partner, since he does not at that time pronounce more than one name. This instinct proves the Existence
of this Creator God and His Oneness.
B. When man wants to take refuge in his Lord and seek shelter with Him, through prayer and asking, we find him only praying to One God, not more than that. We find that he does not call upon any name, but that which can only refer to One God. We find him praying and saying, "Oh Allah!" or "Or Lord!" or something like that, in accord with the Saying of Allah Most High,
Is not He (better than your gods) Who responds to one in distress when he calls on Him, and Who removes the evil, and makes you inheritors of the earth, generations after generations. Is there any god beside Allah? High Exalted is Allah above all they associate as partners (with Him)! * Is not He (better than your so-called gods) Who originates creation, and shall thereafter repeat it, and Who provides for you from heaven and earth? Is there any god ith Allah? Say, "Bring forth your proof, if you are truthful."
[Al-Naml 27: 63-64]
The Arab pagans used to associate with Allah (Mighty & Majestic) many gods in the land, in the form of statues and idols of stone and other materials, which they used t worship alongside Him. If the pagan were asked: How many gods do you worship? He would answer that He is one god in the sky. Then he would list however many he liked of statues and stones which he had taken as false idols that he would worship in the land. However, if he was asked about the god he prayed to and made requests of? He would say: The one in the sky. This proves that man was created to believe in the Oneness of Allah (Glorious & Exalted)
