«إِنَّمَا يَخْشَى اللَّهَ مِنْ عِبَادِهِ الْعُلَمَاءُ»

Misidentifying Allāha as the subject would reverse the intended meaning. The accusative on Allāha and nominative on al-ʿulamāʾu must be established before discussing the restriction signaled by innamā.
A complete answer therefore explains the syntax, the scope of the restriction, and the relationship between knowledge and reverent fear—not merely the label “qasr.”
