نَحْوُ: «ضَارِبُ زَيْدٍ».
Translation: For example, “one who strikes Zayd.”
ضَارِبُ: active participle (ism fāʿil), serving as mudāf. It denotes the agent of striking.
زَيْدٍ: genitive mudāf ilayh, but semantically the object of the action.
Do not read Zayd as the striker. The descriptive head ḍārib refers to the doer; its dependent Zayd is the one struck.
