وَكَذَلِكَ الْمَفْعُولُ بِهِ، نَحْوُ: «هَذَا زَيْدٌ قَائِمًا»؛ فَإِنَّ مَعْنَاهُ: الْمُشَارُ إِلَيْهِ قَائِمًا هُوَ زَيْدٌ.
Translation: Similarly, the object can be semantic: “This is Zayd, standing.” The meaning is that the one pointed to while standing is Zayd.
Qāʾiman describes the person indicated by hādhā; the act of indicating is understood rather than overtly stated.
