And we have sought ˹to reach˺ the heaven but found it filled with powerful guards and burning flames.

وَأَنَّا لَمَسْنَا السَّمَاءَ فَوَجَدْنَاهَا مُلِئَتْ حَرَسًا شَدِيدًا وَشُهُبًا  

قال الجن {وأنا لمسنا السماء} رمنا استراق السمع {فوجدناها ملئت حرسا} من الملائكة {شديدا وشهبا} نجوما محرقة وذلك لما بعث النبي ﷺ .
