﴿ قُل لَّوْ كَانَ مَعَهُۥٓ ءَالِهَةٌۭ كَمَا يَقُولُونَ إِذًۭا لَّٱبْتَغَوْا۟ إِلَىٰ ذِى ٱلْعَرْشِ سَبِيلًۭا ﴾

“Say: "If there were-as some people assert [other] deities side by side with Him, surely [even] they would have to strive to find a way unto Him who is enthroned on His almightiness?"”

Commentary According to the proof of Tauhid (the Oneness of Allah) given in the verse: إِذًا لَّابْتَغَوْا إِلَىٰ ذِي الْعَرْ‌شِ سَبِيلًا (then they would have found out a way to the Lord of the Throne - 42), Allah alone is the creator, owner and master of the entire universe. The argument is if it was not so and He had other partners in this godhead, differences would have necessarily emerged among them. And, in the eventuality of a difference, the whole universal system would have gone to ruins - because, ever abiding peace among them is habitually impossible. Though, this argument has been enunciated here in a prohibitive manner, but there are books of Scholastic Theology (` Ilm al-Kalam) where the logical rationale behind this argument has also been described in great details. The learned may consult these at their discretion.
