Free From Calamities

Bismillaahil-lazee laa yadhurru ma'as-mihi shay'un fil-'ardhi wa laa fis-samaa'i wa Huwas-Samee'ul-'Aleem.

In the Name of Allah, Who with His Name nothing can cause harm in the earth nor in the heavens, and He is All-Hearing, the All-Knowing. (Recite three times in Arabic).

"Whoever recites it three times in the morning will not be afflicted by any calamity before evening, and whoever recites it three times in the evening will not be overtaken by any calamity before morning."
(Abu Dawud 4/332, At-Thirmithi 5/465, Ibn Majah 2/332)
