quran:92:2 –

And ˹by˺ the day when it appears  

and ˹by˺ the day as it unveils, ˹as˺ it is revealed and becomes manifest (idhā, ‘as’, in both instances is an absolute adverbial, operated by the verbal action of the oath),
القرآن:٩٢:٢ –

وَالنَّهَارِ إِذَا تَجَلَّىٰ  

{والنهار إذا تجلى} تكشف وظهر وإذا في الموضوعين لمجرد الظرفية والعامل فيها فعل القسم.
