Abu Dawud, al-Tirmidhi, and others with sound chains. Al-Tirmidhi said, “A good, sound hadith,” and the wording here is that of Abu Dawud.
83_ The tenth: On the authority of Anas (may Allah be pleased with him) who said: The Messenger of Allah (blessings and peace be upon him) said, “Whoever—meaning, when he leaves his house—says, ‘In the name of Allah; I have placed my trust in Allah; there is no power and no might except by Allah,’ it will be said to him, ‘You have been guided, sufficed, and protected,’ and Satan will withdraw from him.” Narrated by Abu Dawud, al-Tirmidhi, al-Nasa’i, and others. Al-Tirmidhi graded it “good.” Abu Dawud adds: “Then the devil says to another devil, ‘What can you do with a man who has been guided, sufficed, and protected?’ ”
Explanation: The point taken from this hadith is the Prophet’s words, “In the name of Allah; I have placed my trust in Allah,” which prove that a person should, upon leaving his house, recite this supplication that embodies reliance upon Allah and seeking His protection. Once outside his home a person is exposed to harm: something may strike him, or an animal—a scorpion, a snake, or the like—may attack him. Therefore he says, “In the name of Allah; I have placed my trust in Allah.” We have already explained that trusting in Allah and depending on Him proceed from confidence in Him and thinking well of Him. His words, “O Allah, I seek refuge in You lest I stray,” mean: lest I myself go astray
