This Ayah is truly a solution to every problem and I say this from my personal experience. When Prophet Yunus (A.S.) recited these words inside the belly of the whale, just think about it: how could a human possibly stay alive inside a whale, deep in the darkness of the ocean? But Allah can do anything. He kept His Prophet alive even in that impossible place.
With deep regret, Prophet Yunus (A.S.) said:
لَا إِلٰهَ إِلَّا أَنْتَ سُبْحَانَكَ إِنِّي كُنْتُ مِنَ الظَّالِمِينَ There is no god but You, Glory be to You; indeed, I was among the wrongdoers.
He admitted his mistake and glorified Allah’s perfection and Allah forgave him. May Allah (SWT) bless us with the eyes to truly see His signs and the heart to thank Him for allowing us to witness His creations. I request everyone to make it a habit to recite this Tasbeeh 100 times a day, especially when you feel anxious or lost. Just pray, surrender your heart infront of Allah and watch how peace replaces your worry.
