The Prophet ﷺ said: When a man goes out of his house and says: "In the name of Allah, I trust in Allah; there is no might and no power but in Allah," the following will be said to him at that time: "You are guided, defended and protected." The devils will go far from him and another devil will say: How can you deal with a man who has been guided, defended and protected? (Using translation from Abū Dāʾūd 5095)
"إذا خرجَ الرجلُ مِنْ بَيته فقال: بِسْم الله، توَّكلتُ على اللهِ، لا حولَ ولا قوَّةَ إلا بالله، فيقَالُ لَهُ: حسْبُكَ، قَدْ هُديتَ، وَكفِيتَ، ووقيتَ، فيتنحَّى له الشَّيطانُ، فيقولُ لَه شَيطَان آخر: كيُف لكَ برجَلٍ قد هُدِى، وَكُفَى، ووُقِى".
