Abu Musa (May Allah be pleased with him) reported:
The Messenger of Allah (ﷺ) said to me, "Shall I not guide you to a treasure from the treasures of Jannah?" I said: "Yes, O Messenger of Allah!" Thereupon he (ﷺ) said, "(Recite) 'La hawla wa la quwwata illa billah' (There is no change of a condition nor power except by Allah)."[Al-Bukhari and Muslim]. (DE)
