Dua for leaving home is recited while going outside of the house that helps you in protection from the evil eye, jinn, saitan, and, also, from the other tribulations of the world.
Narrated by Hazrat Anas Bin Malik (RA) that “Prophet Hazrat Mohammad (ﷺ) said the person who recited this dua while leaving his home, then it is said for him that.
Your sufficiency (kifayat) is done, your guardianship (rehnumai) is done and you have been saved, and then Saitan separates from him and says to his fellow disciples that.
What you can deteriorate or ruin to this person whose guardianship is done by Allah, his sufficiency is done and he is saved from every type of tribulation, you cannot do anything, my disciples.
Sunan Abu Dawud, Hadith No. 5095
