Example 1: وَجَاءَ رَبُّكَ
Reconstruction: jāʾa amru rabbika. Omitted: amr. Word changing case: rabb. Result: nominative subject.
Example 2: وَاسْأَلِ الْقَرْيَةَ
Reconstruction: isʾal ahla al-qaryati. Omitted: ahl. Word changing case: al-qarya. Result: accusative direct object.
Example 3: لَيْسَ كَمِثْلِهِ شَيْءٌ
On the additional-kāf reading, the reconstructed “mithlahu” is an accusative predicate, whereas “mithlihi” is genitive after kāf. On the other reading, kāf retains its normal force and the negation is understood through indirect expression.
