﴿ أَفَلَمْ يَرَوْا۟ إِلَىٰ مَا بَيْنَ أَيْدِيهِمْ وَمَا خَلْفَهُم مِّنَ ٱلسَّمَآءِ وَٱلْأَرْضِ ۚ إِن نَّشَأْ نَخْسِفْ بِهِمُ ٱلْأَرْضَ أَوْ نُسْقِطْ عَلَيْهِمْ كِسَفًۭا مِّنَ ٱلسَّمَآءِ ۚ إِنَّ فِى ذَٰلِكَ لَءَايَةًۭ لِّكُلِّ عَبْدٍۢ مُّنِيبٍۢ ﴾

“Are they, then, not aware of how little of the sky and the earth lies open before them, and how much is hidden from them? [or that,] if We so willed, We could cause the earth to swallow them, or cause fragments of the sky to fall down upon them? In all this, behold, there is a message indeed for every servant [of God] who is wont to turn unto Him [in repentance].”

(Have they not observed) i.e. the disbelievers of Mecca (what is before them) what is above and below them of the sky and the earth (and what is behind them) and what is above and below them (of the sky and the earth? If We will, We can make the earth swallow them, or cause obliteration from the sky to fall on them) and thus destroy them. (Lo! herein) in what I have mentioned concerning the sky and the earth (surely is a portent) a lesson (for every slave who turneth (to Allah) repentant) who hastens to Allah and to His obedience.
