“Once I mentioned fear before Abu ‘Abdillah (a.s.) and he said, ‘I should tell you something that after saying it you will not be frightened during the day or night, say, “In the name of Allah, with (the help of) Allah, I place my trust before Allah; whoever places his trust before Allah, He is suffices him and Allah completes his affairs. Allah has assigned a measure for everything. O Lord, place me under Your protection, in Your neighborhood, include me in Your amnesty and under Your protection.’ I (the narrator) heard the case of a man who had practiced this for thirty years. He did not say it one night and a scorpion bit him.’”
