Sayyiduna Abu Hurairah (may Allah be pleased with him) narrates that the Prophet Muhammad (peace and blessings be upon him) said: "Whoever recites these words: 'There is no deity except Allah, He is One, sovereignty belongs to Him, praise is for Him, and He has power over all things,' whoever recites these words one hundred times daily, he will have the reward equal to freeing ten slaves. One hundred good deeds will be written for him. One hundred sins will be erased, and it will be a means of protection from Satan for him that day until evening. And no one will have done a better deed than this person on that day except someone who recites this phrase more times than him."
