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.”
