عن أنس بن مالك رضي الله عنه مرفوعًا: «من قال -يعني: إذا خَرج من بَيتِه-: بِسم الله تَوَكَّلتُ على اللهِ، وَلاَ حول ولا قُوَّة إِلَّا بالله، يُقَال له: هُدِيتَ وَكُفِيتَ وَوُقِيتَ، وَتَنَحَّى عَنه الشَّيطَان». زاد أبو داود: «فيقول -يعني: الشيطان- لِشَيطان آخر: كَيف لَك بِرَجلٍ قَد هُدِيَ وكُفِيَ ووُقِيَ؟».
The Messenger of Allah (may Allah's peace and blessings be upon him) informs us in this Hadīth that if someone leaves their house and says, "In the name of Allah; I trust in Allah; there is no might and no power save in Allah", an angel will call out to him, saying: O servant of Allah, you have been guided to the straight path, you have been sufficed against your worries, and you have been protected from your enemies.
So the devil assigned to him will move away from him, and another devil will say to the former: How can you misguide someone who has been guided, sufficed, and protected from all of the devils! Because he said those words, you cannot overpower him.
