In Arabic grammar, the word inna is part of a group of sentential abrogators which known as the particles that resemble verbs (الحروف المشبهة بالفعل). These particles come in the beginning of the nominal sentences and change the labels and grammatical states of the subject and predicate. The subject or mubtada which was in the nominative case becomes the ism of inna in the accusative case. The predicate or khabar becomes the khabar of inna and remains in the nominative case.
