Mishkat al-Masabih #2337

Anas reported God’s messenger as saying that when a man goes out of his house and says, "In the name of God; I trust in God; there is no might and no power but in God," the following will be said to him at that time, "You are guided, defended and protected." The devil will go far from him and another devil will say, "How can you deal with a man who has been guided, defended and protected?" Abu Dawud transmitted it, and Tirmidhi transmitted up to “the devil will go far from him."
