Hazrat Abu Huraira (may Allah be pleased with him) narrated that the Messenger of Allah (peace and blessings be upon him) said: Whoever recites this supplication one hundred times during the day — "There is no deity except Allah, alone, He has no partner, His is the dominion and all praise is for Him, and He is powerful over everything" — he will receive a reward equal to freeing ten slaves. One hundred good deeds will be written in his record, and one hundred sins will be erased from him. This supplication will protect him from Satan throughout the day until evening comes, and no one will come with a better deed than this, except for someone who recites this phrase even more than that.
