حَدَّثَنَا عَبْدُ الرَّحْمَنِ بْنُ إِبْرَاهِيمَ الدِّمَشْقِيُّ، حَدَّثَنَا ابْنُ أَبِي فُدَيْكٍ، حَدَّثَنِي هَارُونُ بْنُ هَارُونَ، عَنِ الأَعْرَجِ، عَنْ أَبِي هُرَيْرَةَ، أَنَّ النَّبِيَّ ـ صلى الله عليه وسلم ـ قَالَ ‏"‏ إِذَا خَرَجَ الرَّجُلُ مِنْ بَابِ بَيْتِهِ - أَوْ مِنْ بَابِ دَارِهِ - كَانَ مَعَهُ مَلَكَانِ مُوَكَّلاَنِ بِهِ فَإِذَا قَالَ بِسْمِ اللَّهِ ‏.‏ قَالاَ هُدِيتَ ‏.‏ وَإِذَا قَالَ لاَ حَوْلَ وَلاَ قُوَّةَ إِلاَّ بِاللَّهِ ‏.‏ قَالاَ وُقِيتَ ‏.‏ وَإِذَا قَالَ تَوَكَّلْتُ عَلَى اللَّهِ قَالاَ كُفِيتَ قَالَ فَيَلْقَاهُ قَرِينَاهُ فَيَقُولاَنِ مَاذَا تُرِيدَانِ مِنْ رَجُلٍ قَدْ هُدِيَ وَكُفِيَ وَوُقِيَ ‏"‏ ‏.‏

It was narrated from Abu Hurairah that the Prophet (PBUH) said: “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?’” Translation Not Available
