عَنْ أَبِي تَمِيمَةَ الْهُجَيْمِيِّ عَمَّنْ كَانَ رَدِيفَ النَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ قَالَ كُنْتُ رَدِيفَهُ عَلَى حِمَارٍ فَعَثَرَ الْحِمَارُ فَقُلْتُ: تَعَسَ الشَّيْطَانُ، فَقَالَ لِيَ النَّبِيُّ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ: ((لَا تَقُلْ تَعَسَ الشَّيْطَانُ، فَإِنَّكَ إِذَا قُلْتَ تَعَسَ الشَّيْطَانُ تَعَاظَمَ الشَّيْطَانُ فِي نَفْسِهِ وَقَالَ صَرَعْتُهُ بِقُوَّتِي فَإِذَا قُلْتُ بِسْمِ اللَّهِ تَصَاغَرَتْ إِلَيْهِ نَفْسُهُ حَتَّى يَكُونَ أَصْغَرَ مِنْ ذُبَابٍ (وَفِي لَفْظٍ) تَصَاغَرَ حَتَّى يَصِيرَ مِثْلَ الذُّبَابِ))
Abu Tamimah Hajimi narrates from a companion who was riding behind the Noble Prophet (peace and blessings be upon him), he says: I was riding on a donkey behind the Noble Prophet (peace and blessings be upon him), the donkey stumbled, upon which I said: May the devil perish. But the Noble Prophet (peace and blessings be upon him) said to me: Do not say, "May the devil perish," because when you say, "May the devil perish," the devil begins to consider himself great in his heart and says: I made him fall by my power. But (in such a situation) if you say "Bismillah" (In the name of Allah), the devil's self becomes humiliated, to the extent that he becomes even smaller than a fly. And in another narration, it is mentioned that he becomes so humiliated that he becomes as small as a fly.
