[Machine] Narrated Abu Huraira:

The Prophet ﷺ said, "Whoever says, 'Bismillah hir-Rahman nir-Rahim' (In the name of Allah, the Most Gracious, the Most Merciful), nothing will harm him with that name, whether in the heavens or on the earth, and He is the All-Hearing, the All-Knowing." He said it in the evening and did not get startled by any sudden affliction until the morning. And if he said it in the morning, he did not get startled by any sudden affliction until the evening." Abdullah bin Muslama disagreed with him, so he narrated it from Abu Maudud through a man who heard it from Aban bin Uthman. Abu Maudud also reported that from a man who said, "I heard Aban bin Uthman saying that I heard Uthman bin Affan saying that I heard the Messenger of Allah ﷺ saying something similar to that. Abu Abdur-Rahman told us, and it has been reported from Aban bin Uthman in words other than this." (Source: Jami` at-Tirmidhi 3388)  

عَنِ النَّبِيِّ ﷺ قَالَ مَنْ قَالَ بِاسْمِ اللهِ الَّذِي لَا يَضُرُّ مَعَ اسْمِهِ شَيْءٌ فِي الْأَرْضِ وَلَا فِي السَّمَاءِ وَهُوَ السَّمِيعُ الْعَلِيمُ فَقَالَهَا حِينَ يُمْسِي لَمْ تَفْجَأْهُ فَاجِئَةُ بَلَاءٍ حَتَّى يُصْبِحَ وَإنْ قَالَهَا حِينَ يُصْبِحُ لَمْ تَفْجَأْهُ فَاجِئَةُ بَلَاءٍ حَتَّى يُمْسِيَ [12] خَالَفَهُ عَبْدُ اللهِ بْنُ مَسْلَمَةَ رَوَاهُ عَنْ أَبِي مَوْدُودٍ عَنْ رَجُلٍ عَمَّنْ سَمِعَ أَبَانَ بْنِ عُثْمَانَ 9760 أَخْبَرَنِي مُحَمَّدُ بْنُ عَلِيٍّ قَالَ حَدَّثَنَا الْقَعْنَبِيُّ قَالَ حَدَّثَنَا أَبُو مَوْدُودٍ عَنْ رَجُلٍ قَالَ حَدَّثَنَا مَنْ سَمِعَ أَبَانَ بْنَ عُثْمَانَ يَقُولُ سَمِعْتُ عُثْمَانَ بْنَ عَفَّانَ يَقُولُ سَمِعْتُ رَسُولَ اللهِ ﷺ نَحْوَهُ قَالَ لَنَا أَبُو عَبْدِ الرَّحْمَنِ وَقَدْ رُوِيَ عَنْ أَبَانَ بْنِ عُثْمَانَ بِغَيْرِ هَذَا اللَّفْظِ
