Ibn Asfour (d.669) knew exclamation. As an exaggeration in describing the subject, its cause is hidden, and the exclamation point out of it from analogues. Badr al-Din bin Malik knew him, and he was the son of Nazim al-Millennium. That it is the greatest action of the subject of the apparent merit, and Ibn Hamdoun cited the definition of Ibn Asfour. It is not inclusive because it does not include how do you disbelieve in God, nor about what, peace and blessings of God be upon him, saying: (Glory be to God the believer is not defiled). It is impure, and does not include about what is shortened by the abbreviation of the accusative, because the exclamation in it is from the description of the object and not from the description of the subject, and if it is abnormal, the definition must be included, and that it contains a course for taking the wonder from it in the event of exclamation. The exclamation depends on the object of the exclamation and the exclamation point, the object name derived from the exclamation and the knowledge of its derivative which is the exclamation preceding the knowledge of the derivative and it is the exclamation of it, so the role came, because this definition is to exclamation in a language not a convention. The exclamation, idiomatically, is the expression of the amazed, and grammarians' words are only in terms, not in meaning.
