Dua of Prophet Yunus Calligraphy

لا إلهَ إلا أنتَ سُبْحَانَكَ إِنِّي كُنْتُ مِنَ الظّالِمِيْنَ

‘La ilaha illa anta, subhanaka, inni kuntu minadh-dhalimin’.

He (peace be upon him) is reported to have said in a hadith, recorded by Tirmidhi and others:
The supplication of my brother Dhu al-Nun (YUNIS as) “There is no God but you; Glory be to You; I was one of the wrongdoers”: Every person in a state of distress who has used this supplication has had God remove his distress.
