وَعَنْ أَبَانَ بْنِ عُثْمَانَ قَالَ: سَمِعْتُ أَبِي يَقُولَ: قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ: «مَا مِنْ عَبْدٍ يَقُولُ فِي صَبَاحِ كُلِّ يَوْمٍ وَمَسَاءِ كُلِّ لَيْلَةٍ بِسْمِ اللَّهِ الَّذِي لَا يَضُرُّ مَعَ اسْمِهِ شَيْءٌ فِي الْأَرْضِ وَلَا فِي السَّمَاءِ وَهُوَ السَّمِيعُ الْعَلِيمُ ثَلَاثَ مَرَّاتٍ فَيَضُرَّهُ شَيْءٌ» . فَكَانَ أَبَانُ قَدْ أَصَابَهُ طَرَفُ فَالَجٍ فَجَعَلَ الرَّجُلَ يَنْظُرُ إِلَيْهِ فَقَالَ لَهُ أَبَانُ: مَا تَنْظُرُ إِلَيَّ؟ أَمَا إِنَّ الْحَدِيثَ كَمَا حَدَّثْتُكَ وَلَكِنِّي لَمْ أَقُلْهُ يَوْمَئِذٍ لِيُمْضِيَ اللَّهُ عَلَيَّ قَدَرَهُ. رَوَاهُ التِّرْمِذِيُّ وَابْن مَاجَه وَأَبُو دَاوُد وَفِي رِوَايَته: «لَمْ تُصِبْهُ فُجَاءَةُ بَلَاءٍ حَتَّى يُصْبِحَ وَمَنْ قَالَهَا حِينَ يُصْبِحُ لَمْ تُصِبْهُ فُجَاءَةُ بَلَاءٍ حَتَّى يُمسيَ»

Aban b. ‘Uthman said he heard his father quoting God’s messenger as saying that if anyone says three times every morning and evening, “In the name of God, when whose name is mentioned nothing in earth or heaven can cause harm, and He is the Hearer, the Knower,” he will not be harmed by anything. Aban was afflicted by some paralysis, and when a man began to look at him Aban would say, “Why are you looking at me? The tradition is as I told it to you, but I did not say the words that day in order that God might carry out what He had decreed for me.” Tirmidhi, Ibn Majah and Abu Dawud transmitted it. Abu Dawud’s version has, “He will not suffer sudden affliction till the morning, and if anyone says it in the morning he will not suffer sudden affliction till the evening.”
