وَلَا يَجُوزُ تَقْدِيمُ أَخْبَارِهَا عَلَى أَسْمَائِهَا إِلَّا إِذَا كَانَ ظَرْفًا.
Translation: The predicates of these particles cannot normally be placed before their nouns, except when the predicate is an adverbial/locative expression.
The ordinary order is إِنَّ زَيْدًا قَائِمٌ. Moving the plain adjectival predicate before its ism as إِنَّ قَائِمٌ زَيْدًا violates the source’s normal-order rule. The next slide gives the locative exception.
