In the name of Allah, Most Gracious, Most Merciful.
21:87
وَذَا ٱلنُّونِ إِذ ذَّهَبَ مُغَـٰضِبًا فَظَنَّ أَن لَّن نَّقْدِرَ عَلَيْهِ فَنَادَىٰ فِى ٱلظُّلُمَـٰتِ أَن لَّآ إِلَـٰهَ إِلَّآ أَنتَ سُبْحَـٰنَكَ إِنِّى كُنتُ مِنَ ٱلظَّـٰلِمِينَ
21:87
Dhun Nun went away in anger and thought that We would never have power over him, but in darkness he cried, "Lord, You are the Only God whom I glorify. I have certainly done wrong to myself (so forgive me)". - Muhammad Sarwar (English)
