إِنَّهُ يَعْلَمُ الْجَهْرَ وَمَا يَخْفَىٰ
Indeed He knows what is spoken openly and what remains hidden. (87:7)
Inna strengthens the assertion. The contrast between what is open and what is hidden shows the breadth of divine knowledge. The pairing is semantically meaningful rather than an arbitrary coordination.
Placed after the reference to divine will, the sentence provides a fitting contextual explanation. Yet emphasis is not automatically exclusivity: an emphatic report with “inna” must not be mislabeled as a formal restriction.
