Narrated Anas ibn Malik: The Prophet ﷺ said: When a man goes out of his house and says: "In the name of Allah, I trust in Allah; there is no might and no power but in Allah, " the following will be said to him at that time: "You are guided, defended and protected. " The devils will go far from him and another devil will say: How can you deal with a man who has been guided, defended and protected?

´Anas bin Malik narrated that the Messenger of Allah (ﷺ) said:` “Whoever says – that is: when he leaves his house – ‘In the Name of Allah, I place my trust in Allah, there is no might or power except by Allah (Bismillāh, tawakkaltu `alallāh, lā ḥawla wa lā quwwata illā billāh)’ it will be said to him: ‘You have been sufficed and protected,’ and Shaitan will become distant from him.”
Shaykh Dr. Abdur Rahman Freywai
Explanation: 1: I began with the name of Allah, I placed my trust in Allah, and there is no power to avoid sins nor strength to perform any good deed except with the support of Allah.
