Quranic verse: "Nun. By the pen and what they inscribe," by Mohammad Ehsai this is a verse from the Holy Quran of Surat "Al Qalam"; The Pen. Noon is the letter "N" looks like a cup with a dot above. It's meanings and symbolisms in Islam, Arabic, and Arabic Mysticism are vast. It is called "Noon A-Nisswah" which means the Feminine N as it is added at the end of a word to pluralize its feminine form. In addition, it denotes education as I recall reading in a hadith of the Prophet Mohammed.
