The prophet (saw) gave us this beautiful remembrance to start off our day outside of the home. When you say
بسم الله، توكلت على الله، لا حول ولا قوة إلا بالله
Bismillah, tawakkaltu ’ala Allah, wa la hawla wa la quwwata illa-billah
In the name of Allah, I’ve put my trust in Allah, and there is no power or might except that which belongs to Allah.
And the angels responding saying you’ve been guided you will be defended. You will be protected and your shaitan knowing that you are going to be under the protection of the angels and the guidance of Allah subhanahu wa’ta’ala throughout the day.
