﴿ إِنَّ ٱللَّهَ لَا يَخْفَىٰ عَلَيْهِ شَىْءٌۭ فِى ٱلْأَرْضِ وَلَا فِى ٱلسَّمَآءِ ﴾

“Verily, nothing on earth or in the heavens is hidden from God.”

Nothing no existent thing whatever is hidden in heaven and earth from God on account of His knowledge of universals and particulars. God specifies them heaven and earth because sensory perception does not go beyond these.
