نَحْوُ: «جَاءَ الْبَرْدُ وَالْجُبَّاتِ»، وَ«جِئْتُ أَنَا وَزَيْدًا»، أَيْ: مَعَ الْجُبَّاتِ وَمَعَ زَيْدٍ.
Translation: For example: “The cold arrived along with the cloaks,” and “I came with Zayd”; that is, together with the cloaks and with Zayd.
These are source examples. The kasra on al-jubbāti marks the accusative of a sound feminine plural, not a genitive.
