لَا حَوْلَ وَلَا قُوَّةَ إِلَّا بِاللَّهِ

Laa hawla wa laa quwwata 'illaa billaah

There is no might nor power except with Allah. The Prophet (ﷺ) said, “O 'Abdullah ibn Qays! Shall I not inform you of one of the treasures of Paradise? ” I said, "Surely, O Messenger of Allah." He said, "Say it." - (The dua is mentioned above)
