Al-An'aam 6:73

It is He Who created the heavens and earth for a true purpose. On the Day [of Resurrection] He will say, “Be,” and it will be. His word is the truth. His is the dominion on the Day the Trumpet will be blown. He is the Knower of the unseen and the seen, and He is the All-Wise, the All-Aware.”

And it is He who created the heavens and earth in truth. And the day [i.e., whenever] He says, "Be," and it is, His word is the truth.[319] And His is the dominion [on] the Day the Horn is blown. [He is] Knower of the unseen[320] and the witnessed;[321] and He is the Wise, the Aware.

[319] When interpreted as the "Day" (of resurrection), the sentence would read: "And the Day He says, 'Be,' and it is, His word will be the truth."
[320] That which is absent, invisible, or beyond the perception of the senses or of the mind and therefore is unknown to man, except for what Allāh chooses to reveal.
[321] What is present, visible and known to man. The knowledge of Allāh (subḥānahu wa taʿālā) includes the reality of all things and all occurrences, no matter how they might appear to human beings.

73. It is He Who has created the heavens and the earth in truth, and on the Day (i.e. the Day of Resurrection) He will say: "Be!", - and it is! His Word is the Truth. His will be the dominion on the Day when the Trumpet will be blown. All-Knower of the unseen and the seen. He is the All-Wise, Well-Aware (of all things).

He it is Who created the heavens and the earth in truth. In the day when He saith: Be! it is. His Word is the Truth, and His will be the Sovereignty on the day when the trumpet is blown. Knower of the Invisible and the Visible, He is the Wise, the Aware.
