In the Name of Allah, with whose Name nothing can harm in the earth nor in the sky. He is The All-Hearing and All-Knowing.

Abān b. ʿUthmān narrated from ʿUthmān b. ʿAffān (raḍiy Allāhu ʿanhu) who mentioned that the Messenger of Allah ﷺ said: “There is no servant who says [the above] three times every morning and evening, except that nothing will harm him.” Abān himself had been afflicted with a form of paralysis, so the man began to look at him. Abān said to him: “Why do you look at me? The ḥadīth is as I have narrated it to you, except that I did not recite it one day, and Allah brought about His decree upon me.” (Tirmidhī 3388) The Messenger of Allah ﷺ said: “Whoever says [the above] three times (in the evening), they will not be afflicted by a sudden calamity till the morning. And whoever says it three times in the morning, they will not be afflicted with a sudden calamity until the evening.” (Abū Dāwūd 5088)
