وَيَجُوزُ حَذْفُ الْعَائِدِ مِنَ اللَّفْظِ إِنْ كَانَ مَفْعُولًا.
Translation: An object ʿāʾid may be omitted from the surface wording.
Omission means the pronoun is unspoken but understood.
Do not extend this particular rule to deleting a returning subject: the text explicitly specifies an object ʿāʾid.
