Mistake 1: putting the promoted noun in the accusative: «ضُرِبَ زَيْدًا» instead of ضُرِبَ زَيْدٌ.
Mistake 2: treating Zayd as the semantic striker; he is the person struck.
Mistake 3: forcing a dual/plural verb before every overt dual/plural passive subject; in ordinary verb-initial order, the verb remains singular.
