From Sahih Muslim (Hadith 6868):
Abu Musa Ash'ari reported that Allah's Messenger (ﷺ) said to him:Should I not direct you to the words from the treasures of Paradise, or he said: Like a treasure from the treasures of Paradise? I said: Of course, do that. Thereupon he said:" There is no might and no power but that of Allah
