ن و نn-w-n
— نُوْنnūn: fish; and «ذُو النُّوْنdhū an-nūn» is the epithet of the Prophet Yūnus (peace be upon him), i.e. the man of the fish. Also «nūn» is one of the disjointed letters (ḥurūf muqaṭṭaʿāt), at the opening of Sūrat al-Qalam. Only once in the Quran as a noun: ﴿وَذَا النُّوْنِ إِذْ ذَّهَبَ مُغَاضِبًا﴾ (Al-Anbiyāʾ 21:87).
