حَدَّثَنَا عَبْد اللَّهِ حَدَّثَنِي مُحَمَّدُ بْنُ إِسْحَاقَ الْمُسَيَّبِيُّ حَدَّثَنَا أَنَسُ بْنُ عِيَاضٍ عَنْ أَبِي مَوْدُودٍ عَنْ مُحَمَّدِ بْنِ كَعْبٍ عَنْ أَبَانَ بْنِ عُثْمَانَ عَنْ عُثْمَانَ أَنَّ النَّبِيَّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ قَالَ مَنْ قَالَ بِسْمِ اللَّهِ الَّذِي لَا يَضُرُّ مَعَ اسْمِهِ شَيْءٌ فِي الْأَرْضِ وَلَا فِي السَّمَاءِ وَهُوَ السَّمِيعُ الْعَلِيمُ ثَلَاثَ مَرَّاتٍ لَمْ تَفْجَأْهُ فَاجِئَةُ بَلَاءٍ حَتَّى اللَّيْلِ وَمَنْ قَالَهَا حِينَ يُمْسِي لَمْ تَفْجَأْهُ فَاجِئَةُ بَلَاءٍ حَتَّى يُصْبِحَ إِنْ شَاءَ اللَّهُ
مسند امام احمد بن حنبل · Hadith 528
It was narrated from Aban bin 'Uthman, from 'Uthman, that the Prophet (PBUH) said: "Whoever 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,' 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 sha' Allah."
