It was narrated that Abu Musa said: "The Prophet (saas) heard me saying: “La hawla wa la quwwata illa billah (there is no power and no strength except with Allah).' He said: “O 'Abdullah bin Qais! Shall I not tell you of a word which is one of the treasures of Paradise?' I said: “Yes, O Messenger of Allah.' He said: “Say: La hawla wa la quwwata illa billah (There is no power and no strength except with Allah)””””"
