(Al-Qalam) 68 : 1
بِسْمِ اللَّهِ الرَّحْمَٰنِ الرَّحِيمِ ن ۚ وَالْقَلَمِ وَمَا يَسْطُرُونَ
“Noon”, by the Pen and what they are writing!
It is told in verse 21: 87 about prophet Yoonus as the man of fish when he went off angrily. So the Arabic alphabet “Noon” refers the man of fish mentioned there. And it is told in the 48th verse of this Surah that you should not be like the companion of the fish. So “Noon” refers prophet Yoonus who was swallowed by a huge fish-whale. See explanation 16: 89; 25: 33; and 52: 2.
