1. قَامَ زَيْدٌ: the verb “qāma” precedes; standing proceeds from Zayd; Zayd is the fāʿil.
2. زَيْدٌ ضَارِبٌ أَبُوهُ عَمْرًا: the governing descriptive form is “ḍārib”; the striking proceeds from his father; أبوه is the participle’s fāʿil.
3. مَا ضَرَبَ زَيْدٌ عَمْرًا: the verb “ḍaraba” precedes; Zayd is the fāʿil and ʿAmr is the object.
One definition accounts for all three structures.
