أَزَيْدٌ قَائِمٌ
Is Zayd standing?
Hamza can request assent before a nominal sentence too. Zaydun is the subject of predication (mubtadaʾ), qāʾimun its predicate (khabar), and the question is whether the attributed state is true.
Verbal versus nominal sentence structure does not itself decide taṣawwur or taṣdīq. Both “A-qāma Zaydun?” and “A-Zaydun qāʾimun?” may ask for a judgment about the relationship.
