quran:56:76 –

And indeed, it is an oath - if you could know - ˹most˺ great.  

And indeed it, the swearing by these ˹setting-places of stars˺, is a tremendous oath, if you only knew — if you were people of ˹deep˺ knowledge, you would realise the magnitude of this oath.
القرآن:٥٦:٧٦ –

وَإِنَّهُ لَقَسَمٌ لَوْ تَعْلَمُونَ عَظِيمٌ  

{وإنه} أي القسم بها {لقسم لو تعلمون عظيم} لو كنتم من ذوي العلم لعلمتم عظم هذا القسم.
