Disagreements of Grammarians' Rules in (Noon) Letter

Abstract

No letter has enjoyed abundant study in grammatical, audio, morphological, semantic, Qur'anic readings, intonation, and other Arabic studies as the noon letter. Noon has been studied thoroughly in terms of its sense, divisions, and meanings for which it came.

However, the noon that received these studies came in my research following the places that the noon violated its linguistic rule. The noon, as mentioned in the books of various studies, is nothing more than being in general a sound phenomenon. However, as the habit of Arabic rules, they sometimes comes with permitting and perforating the rule!
