PROPHET MUHAMMAD (ﷺ) said:

If one says one hundred times in a day

1) Will get the reward of manumitting ten slaves, and
2) One hundred good deeds will be written in his account, and
3) One hundred bad deeds will be wiped off or erased from his account, and
4) On that day he will be protected from the morning till evening from Satan, and
5) Nobody will be superior to him except one who has done more than that which he has done.
