Dua when Leaving the House
Anas ibn Maalik (Radhi Allah Anh) reported: Prophet Muhammad (Sal Allahu Alayhi Wa Sallam) said, “Whoever says upon leaving his house:
بِسْمِ اللّٰهِ، تَوَكَّلْتُ عَلَى اللّٰهِ، وَلَا حَوْلَ وَلَا قُوَّةَ إِلَّا بِاللّٰهِ
Bismillaahi, tawakkaltu 'alallaahi, wa laa hawla wa laa quwwata illaa billaah
In the Name of Allah, I have placed my trust in Allah; there is no might and no power except by Allah.
it will be said to him: ‘You are guided, defended and protected.’ The devil will go far away from him.”
Abu Dawud report it with this addition: “One devil will say to another: ‘How can you deal with a man who has been guided, defended and protected?’”
