هَلْ قَامَ زَيْدٌ؟ وَهَلْ عَمْرٌو قَاعِدٌ؟
Has Zayd risen? And is ʿAmr seated?
The first example applies hal to a verbal clause beginning with qāma. The second applies it to a nominal clause with ʿAmr as subject and qāʿid as predicate. Both request confirmation of the predication.
Hal is therefore not restricted to verbs. Yet an ordinary nominal predicate and a fronted noun followed by a verb pose different rhetorical issues; the latter is examined separately.
