The Prophet (Allah bless him and give him peace) said, “The supplication of my brother Dhun Nun (Yunus, peace be upon him), who called on Allah while in the whale’s belly: ‘There is no deity but You. Glory be to You! Verily, I have been among the wrongdoers’ (Quran 21:87) – no Muslim person says it, for any situation whatsoever, except that Allah Most High answers his call.” [Tirmidhi]
لا إلهَ إلا أنتَ سُبْحَانَكَ إِنِّي كُنْتُ مِنَ الظّالِمِيْنَ
La ilaha illa Anta, Subhanaka, inni kuntu mina z-zalimin
