Ibn Taymiyya narrated, 'When the angels were commanded to bear the Throne [of God], they said: "Our Lord, how can we bear Your Throne when upon it is Your greatness and might?" He said, "Say: lâ hawla wa lâ quwwata illâ bi Allâh (There is neither power nor strength save in God.)" Upon pronouncing this, they carried the Throne.'
These words have the striking effect of helping one to accomplish difficult work, bear fatigue, visit kings and endure fear or dreadful experience. They also have the striking effect of warding off poverty. For according to a hadith related by Ibn Abi l-Dunya, the Messenger of God said, 'For whoever says "There is neither strength nor power save in God" one hundred times, no day shall be afflicted by poverty.'
