Indeed, Allah knows the unseen ˹aspects˺ of the heavens and the earth. And Allah is Seeing of what you do.  

Truly God knows the Unseen of the heavens and the earth, that is, ˹He knows˺ all that is hidden in both, and God is Seer of what you do’ (may be read either as ya‘malūna, ‘they do’, or ta‘malūna, ‘you do’), nothing of which can be concealed from Him.

إِنَّ اللَّهَ يَعْلَمُ غَيْبَ السَّمَاوَاتِ وَالْأَرْضِ ۚ وَاللَّهُ بَصِيرٌ بِمَا تَعْمَلُونَ
