The ‘Nuun’ of the 1st person or majestic ‘nuun’ is one of the letters signifying the present tense. It is used by the speaker whenever he intends to attach the verb to himself for self veneration or for the 1st person plural (we) masculine or feminine or a mixture of both, or when he wants to indicate his own greatness or self esteem [1]. The seven authorities in Qur’anic recitation have used it in various places in the Glorious Quran. They differ in its application. Some of them use it, but others use other letters of the present tense in their recitations. This article aims at exploring the secret of their differences and reviewing the linguistic phenomenon itself. The article consists of an introduction and case study of some areas where the authorities recited differently.
