“O eminent ones! I know of no god for you other than myself.” [al-Qasas 28:38]
He said this out of sheer obstinacy. There is no benefit in arguing with one who is obstinate. Otherwise, how could any rational person, who reflects even a little, deny the lordship of Allah, Mighty and Majestic is He?
This immense universe—with its heaven and earth, its stars, sun, moon, seas, rivers, trees, mountains, and lowlands—could it have no Creator?! Were all creation to gather together to create the like of the smallest star or planet in the sky, they would have no power to do so. And if all the equipment of creation were brought together to produce this air that fills the region, and to bring this violent wind that uproots trees and demolishes tents, they would be unable to do so. Who brought it except Allah, Glorified and Exalted is He?!
But I say: there is no benefit in debating the obstinate, stubborn person, for he will say, “I do not concede,” and then leave. Thus, whoever denies the lordship of Allah is undoubtedly a disbeliever. Indeed, he is worse than one who associates partners with Allah, because the polytheist has affirmed some of the truth, whereas this person has denied all of it. Whoever denies the lordship of Allah, then, there is no doubt about his disbelief.
His statement: “or His oneness.” Likewise, whoever denies His oneness. Perhaps the author intends here by oneness the oneness of divinity, because if by denying oneness he meant associating partners with Allah, this would be repetitive in light of his statement, “Whoever associates partners with Allah.” But since he mentioned lordship, then oneness, then the attributes, it appears that by oneness here he means the oneness of divinity: that is, whoever denies that the only deity is Allah has disbelieved. This includes one who believes, says, or does something indicating that he holds there to be some object of worship besides Allah that deserves to be worshipped—such as those who worship al-Lat, al-‘Uzza, and Manat, drawing near to them through sacrifice, bowing, and prostration. As for supplication, it is an act of worship and has a connection to lordship.
