What is the difference between the nominal sentence's indication of continuity and permanence, and the verbal sentence that begins with a present tense verb, indicating the evocation or repetition of a state?

A nominal sentence (jumlah ismiyyah) conveys permanence and stability. It may also indicate occurrence and renewal if its predicate (khabar) is a verbal sentence (jumlah fi'liyyah), or if there is a contextual indicator (qarinah) to that effect. As for the verbal sentence, in its originalوضع (وضع), it indicates continuity and occurrence, similar to how the present tense verb (al-fi'l al-mudari') signifies occurrence in the future, and the past tense verb (al-fi'l al-madi) signifies occurrence in the past. A verbal sentence may also convey continuous renewal through contextual indicators.
