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?  

أَنَّ النَّبِيَّ ﷺ قَالَ إِذَا خَرَجَ الرَّجُلُ مِنْ بَيْتِهِ فَقَالَ بِسْمِ اللَّهِ تَوَكَّلْتُ عَلَى اللَّهِ لاَ حَوْلَ وَلاَ قُوَّةَ إِلاَّ بِاللَّهِ قَالَ يُقَالُ حِينَئِذٍ هُدِيتَ وَكُفِيتَ وَوُقِيتَ فَتَتَنَحَّى لَهُ الشَّيَاطِينُ فَيَقُولُ لَهُ شَيْطَانٌ آخَرُ كَيْفَ لَكَ بِرَجُلٍ قَدْ هُدِيَ وَكُفِيَ وَوُقِيَ  

“When a man goes out of the door of his house, there are two angels with him who are appointed over him. If he says Bismillah (in the Name of Allah) they say: ‘You have been guided.’ If he says La hawla wa la quwwata illa billah (there is no power and no strength except with Allah), they say: ‘You are protected.’ If he says, Tawwakaltu ‘ala Allah (I have my trust in Allah), they say: ‘You have been taken care of.’ Then his two Qarins (satans) come to him and they (the two angels) say: ‘What do you want with a man who has been guided, protected and taken care of?’” (Using translation from Ibn Mājah 3886)   

"إِذا خرجَ الرَّجلُ من بابِ بيته أو مِنْ بابِ دَارِهِ كان معه مَلكانِ مُوكَّلانِ به، فإِذا قال: بسْم الله قالا: هُديتَ، وإِذا قال: لا حَوْلَ ولا قوَّةَ إِلا بالله، قالا: وُقِيتَ، وإذا قال: توكلَّتُ على اللهِ قَالا: كُفِيتَ. فتلقَّاهُ قَرِيناهُ فيقولانِ: مَا تُرِيدَان مِنْ رَجُلٍ قد هُدِى، وكفِى، ووُقِى".
