Explanation of the author's (may Allah have mercy on him) statement: " . . .

The Shaykh : The author (may Allah have mercy on him) said: "And there are five signs of the accusative case". The accusative case is one of the types of inflection. The categories of inflection are nominative, accusative, genitive, and jussive. We have finished discussing the nominative case, my brothers. How many signs does the nominative case have? Four: the dammah, the waw, the alif, and the noon. The author says regarding the accusative: "five signs". You will find this easy because it is a review of what came before. "The fathah, the alif, the kasrah, the yaa, and the deletion of the noon". These are five signs, and what indicated them was tracking and induction, because the scholars of Arabic (may Allah have mercy on them) tracked the speech of the Arabs and found that the accusative does not go beyond these five things. The fathah is the original sign, and the rest are substitutes for it. The fathah, the alif, the kasrah, the yaa, and the deletion of the noon. He did not say "the presence of the noon"; the presence of the noon is a sign of the nominative case, but the accusative is the deletion of the noon.
