"Whoever says, 'La ilaha illallah, wahdahu la sharika lah, lahul-mulku wa lahul-hamd, wa huwa 'ala kulli shay'in qadir'  a hundred times during a day will have a reward equivalent to the reward for freeing ten slaves, a hundred good deeds will be recorded for him and a hundred bad deeds of his will be wiped off, nd it will be a safeguard for him from Satan that day until evening, and none shall come with anything better except someone who has done more"
