Allah's omniscience and all-encompassing knowledge

وَلِلَّهِ مَا فِى ٱلسَّمَـٰوَٰتِ وَمَا فِى ٱلْأَرْضِ ۚ وَكَانَ ٱللَّهُ بِكُلِّ شَىْءٍ مُّحِيطًا

And to Allāh belongs whatever is in the heavens and whatever is on the earth. And ever is Allāh, of all things, encompassing.

قُلْ كَفَىٰ بِٱللَّهِ شَهِيدًۢا بَيْنِى وَبَيْنَكُمْ ۚ إِنَّهُۥ كَانَ بِعِبَادِهِۦ خَبِيرًۢا بَصِيرًا

Say, "Sufficient is Allāh as Witness between me and you. Indeed He is ever, concerning His servants, Aware and Seeing."

هُوَ ٱلْأَوَّلُ وَٱلْـَٔاخِرُ وَٱلظَّـٰهِرُ وَٱلْبَاطِنُ ۖ وَهُوَ بِكُلِّ شَىْءٍ عَلِيمٌ

He is the First and the Last, the Ascendant and the Intimate, and He is, of all things, Knowing.
