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."
Sahih Muslim Book 48, Hadith 62
← Previous Hadith " He (the Holy Prophet) said: He Whom you are sup- plicating is nearer to every one of you than the neck of his camel." And there is no mention of these words:" There is no might and no power but that of Allah."

Sahih Muslim Book 48, Hadith 61 Next Hadith → Teach me a supplication which I should recite in my prayer. Thereupon he (the Holy Prophet) said: Recite:" O Allah, I have done great wrong to myself." According to Qutaiba (the words were: ) much (wrong) -there is none to forgive the sins but Thou only, say:" Grant me pardon from Thyself, have mercy upon me for Thou art much Forgiving and Compassionate."
