Sayyiduna Uqbah bin Amir (may Allah be pleased with him) said that the Messenger of Allah (peace and blessings be upon him) said: "Whoever Allah Almighty has blessed with a favour and wishes for it to remain, let him frequently say: 'La hawla wa la quwwata illa billah' (There is no might and no power except with Allah)." Then the Messenger of Allah (peace and blessings be upon him) recited this verse: "And why did you not say, when you entered your garden: 'What Allah wills; there is no power except with Allah'" [al-Kahf: 39].
