COMMENTARY on 39:67
A. Yusuf Ali:

Translation:
No just estimate have they made of Allah, 4341 such as is due to Him: On the Day of Judgment the whole of the earth will be but His handful, 4342 and the heavens will be rolled up in His right hand: Glory to Him! High is He above the Partners they attribute to Him!
Commentary:

4341  Cf. 6:91, and n. 909; and 22:74. In running after false gods or the powers of nature they have forgotten that all creatures are as nothing before Allah.

4342  See last note. The whole earth will be no more to Allah than a thing that a man might enclose in the hollow of his hand, nor will the heavens with their vast expanse be more than a scroll, which a man might roll up with his right hand, the hand of power and action. Cf. 21:104, and 81:1. (R).

 

Muhammad Asad:

Translation:
And no true understanding of God have they [who worship aught beside Him], inasmuch as the whole of the earth will be as a [mere] handful to Him on Resurrection Day, and the heavens will be rolled up in His right hand: 66 limitless is He in His glory, and sublimely exalted above anything to which they may ascribe a share in His divinity!
Commentary:
66  I.e., the whole universe is as nothing before Him: for this specific allegory of God’s almightiness, see 21:104. There are many instances, in the Qur’an as well as in authentic ahadith, of the clearly metaphorical use of the term "hand" in allusions to God’s absolute power and dominion. The particular reference, in the above, to the Day of Resurrection is due to the fact that it will be only on his own resurrection that a human being shall fully grasp the concept of God’s almightiness, referred to in the subsequent words, "limitless is He in His glory" (subhanahu)".
