"I heard the Messenger of Allah (saas) say: "There is no person who says, in the morning and evening of every day: Bismillahil-ladhi la yadurru ma'a ismihi shay'un fil-ardi wa la fis-sama'i wa Huwas-Sami'ul-'Alim (In the name of Allah with Whose Name nothing on earth or in heaven harms, and He is the All-Seeing, All-Knowing), three times, and is then harmed by anything.'" (Hasan)He (one of the narrators) said: "Aban had been stricken with paralysis on one side of his body, and a man started looking at him. Aban said: 'Why are you looking at me? The Hadith is as I have narrated it to you, but I did not say it that day, so that the decree of Allah might be implemented.'"  

سَمِعْتُ رَسُولَ اللَّهِ ﷺ يَقُولُ مَا مِنْ عَبْدٍ يَقُولُ فِي صَبَاحِ كُلِّ يَوْمٍ وَمَسَاءِ كَلِّ لَيْلَةٍ بِسْمِ اللَّهِ الَّذِي لاَ يَضُرُّ مَعَ اسْمِهِ شَىْءٌ فِي الأَرْضِ وَلاَ فِي السَّمَاءِ وَهُوَ السَّمِيعُ الْعَلِيمُ ثَلاَثَ مَرَّاتٍ فَيَضُرَّهُ شَىْءٌ قَالَ وَكَانَ أَبَانُ قَدْ أَصَابَهُ طَرَفٌ مِنَ الْفَالِجِ فَجَعَلَ الرَّجُلُ يَنْظُرُ إِلَيْهِ فَقَالَ لَهُ أَبَانُ مَا تَنْظُرُ إِلَىَّ أَمَا إِنَّ الْحَدِيثَ كَمَا قَدْ حَدَّثْتُكَ وَلَكِنِّي لَمْ أَقُلْهُ يَوْمَئِذٍ لِيُمْضِيَ اللَّهُ عَلَىَّ قَدَرَهُ  

The Messenger of Allah ﷺ said: ʿWhoever says in the Name of Allah, with whose name nothing on earth or in heaven can cause harm, and He is the All-Hearing, All-Knowing, nothing will harm him.ʿ  

قَالَ رَسُولُ اللهِ ﷺ مَنْ قَالَ بِسْمِ اللهِ الَّذِي لَا يَضُرُّ مَعَ اسْمِهِ شَيْءٌ فِي الْأَرْضِ وَلا فِي السَّمَاءِ وَهُوَ السَّمِيعُ الْعَلِيمُ لَمْ يَضُرَّهُ شَيْءٌ  

I heard ʿUthman bin ʿAffan ؓ say: The Messenger of Allah ﷺ said: ʿWhoever says at the beginning of the day or the beginning of the night, ‘In the Name of Allah with Whose name nothing on earth or in heaven can cause harm, and he is the All-Hearing. All-Knowing.ʿ three times, nothing will harm him during that day or that night.”  

قَالَ رَسُولُ اللهِ ﷺ مَنْ قَالَ فِي أَوَّلِ يَوْمِهِ أَوْ فِي أَوَّلِ لَيْلَتِهِ بِسْمِ اللهِ الَّذِي لَا يَضُرُّ مَعَ اسْمِهِ شَيْءٌ فِي الْأَرْضِ وَلا فِي السَّمَاءِ وَهُوَ السَّمِيعُ الْعَلِيمُ ثَلاثَ مَرَّاتٍ لَمْ يَضُرَّهُ شَيْءٌ فِي ذَلِكَ الْيَوْمِ أَوْ فِي تِلْكَ اللَّيْلَةِ  

ʿWhoever says, ʿIn the Name of Allah with Whose name nothing on earth or in heaven can cause harm, and he is the All-Hearing, All-Knowing.ʿ three times, will not be struck unawares by calamity until night comes, and whoever says it in the evening will not be struck unawares by calamity until morning comes, in shaʿ Allah.” (Using translation from Aḥmad 528)   

أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ «مَنْ قَالَ حِينَ يُصْبِحُ بِسْمِ اللَّهِ الَّذِي لَا يَضُرُّ مَعَ اسْمِهِ شَيْءٌ فِي الْأَرْضِ وَلَا فِي السَّمَاءِ وَهُوَ السَّمِيعُ الْعَلِيمُ ثَلَاثَ مَرَّاتٍ لَمْ تَفْجَأْهُ فَاجِئَةُ بَلَاءٍ حَتَّى يُمْسِيَ وَإِنْ قَالَهَا حِينَ يُمْسِي لَمْ تَفْجَأْهُ فَاجِئَةُ بَلَاءٍ حَتَّى يُصْبِحَ»  

ʿWhoever says, ʿIn the Name of Allah with Whose name nothing on earth or in heaven can cause harm, and he is the All-Hearing, All-Knowing.ʿ three times, will not be struck unawares by calamity until night comes, and whoever says it in the evening will not be struck unawares by calamity until morning comes, in shaʿ Allah.” (Using translation from Aḥmad 528)   

قَالَ رَسُولُ اللَّهِ ﷺ «مَنْ قَالَ حِينَ يُصْبِحُ ثَلَاثَ مَرَّاتٍ بِسْمِ اللَّهِ الَّذِي لَا يَضُرُّ مَعَ اسْمِهِ شَيْءٌ فِي الْأَرْضِ وَلَا فِي السَّمَاءِ وَهُوَ السَّمِيعُ الْعَلِيمُ لَمْ تَفْجَأْهُ فَاجِئَةُ بَلَاءٍ حَتَّى يُمْسِيَ وَمَنْ قَالَهَا حِينَ يُمْسِي لَمْ تَفْجَأْهُ فَاجِئَةُ بَلَاءٍ حَتَّى يُصْبِحَ»  

"مَن قَال إِذَا أَصبَحَ وَإِذَا أَمسَى ثَلَاثَ مَرَّات: بِسمِ الله الَّذِي لا يَضُرُّ مَعَ اسمِهِ شَيءٌ في الأَرْضِ ولا في السَّمَاءِ، وَهُوَ السَّمِيعُ الْعَلِيمُ، لَم يُصِبهُ في يَومِهِ وَلا في ليلَتِهِ شيءٌ".  

"ما مِنْ عبْدٍ يقُولُ فِي (*) صباحٍ في كُلِّ يوْمٍ، ومساء كُلِّ لَيلَةٍ: بِسْمِ اللهِ الَّذِي لا يضُرُّ مع اسْمِهِ شيءٌ فِي الأَرْضِ ولا فِي السَّماءِ وهُوَ السَّمِيعُ الْعَلِيم ثلاثَ مرَّاتٍ فَلا يضُرَّهُ شَيءٌ".
