from the Prophet ﷺ who said: "If anyone says in the morning or in the evening: 'O Allah! You are my Lord; there is no god except You, You have created me, and I am Your servant and I hold on to Your covenant and promise as much as I can; I seek refuge in You from the evil of what I have done: I acknowledge Your favour upon me, and I acknowledge my sin. So pardon me, for none but You pardons sins,' and he dies during the daytime or during the night, he will enter Paradise."  

عَنِ النَّبِيِّ ﷺ قَالَ: «مَنْ قَالَ حِينَ يُصْبِحُ أَوْ حِينَ يُمْسِي: (اللَّهُمَّ أَنْتَ رَبِّي لاَ إِلَهَ إِلاَّ أَنْتَ، خَلَقْتَنِي وَأَنَا عَبْدُكَ وَأَنَا عَلَى عَهْدِكَ وَوَعْدِكَ مَا اسْتَطَعْتُ، أَعُوذُ بِكَ مِنْ شَرِّ مَا صَنَعْتُ، أَبُوءُ بِنِعْمَتِكَ وَأَبُوءُ بِذَنْبِي، فَاغْفِرْ لِي إِنَّهُ لاَ يَغْفِرُ الذُّنُوبَ إِلاَّ أَنْتَ) فَمَاتَ مِنْ يَوْمِهِ أَوْ مِنْ لَيْلَتِهِ دَخَلَ الْجَنَّةَ۔»  

that the Prophet ﷺ 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 unaware by calamity until night comes, and whoever says it in the evening will not be struck unaware by calamity until morning comes, Allah Willing.”  

أَنَّ النَّبِيَّ ﷺ قَالَ: «مَنْ قَالَ: (بِسْمِ اللهِ الَّذِي لَا يَضُرُّ مَعَ اسْمِهِ شَيْءٌ فِي الْأَرْضِ وَلا فِي السَّمَاءِ وَهُوَ السَّمِيعُ الْعَلِيمُ) ثَلاثَ مَرَّاتٍ، لَمْ تَفْجَأْهُ فَاجِئَةُ بَلاءٍ حَتَّى اللَّيْلِ، وَمَنْ قَالَهَا حِينَ يُمْسِي لَمْ تَفْجَأْهُ فَاجِئَةُ بَلاءٍ حَتَّى يُصْبِحَ إِنْ شَاءَ اللهُ۔»
