Regarding The Mu'awwidhatain
حَدَّثَنَا عَبْدُ اللَّهِ بْنُ مُحَمَّدٍ النُّفَيْلِيُّ، حَدَّثَنَا مُحَمَّدُ بْنُ سَلَمَةَ، عَنْ مُحَمَّدِ بْنِ إِسْحَاقَ، عَنْ سَعِيدِ بْنِ أَبِي سَعِيدٍ الْمَقْبُرِيِّ، عَنْ أَبِيهِ، عَنْ عُقْبَةَ بْنِ عَامِرٍ، قَالَ بَيْنَا أَنَا أَسِيرُ، مَعَ رَسُولِ اللَّهِ صلى الله عليه وسلم بَيْنَ الْجُحْفَةِ وَالأَبْوَاءِ إِذْ غَشِيَتْنَا رِيحٌ وَظُلْمَةٌ شَدِيدَةٌ فَجَعَلَ رَسُولُ اللَّهِ صلى الله عليه وسلم يَتَعَوَّذُ بِـ { أَعُوذُ بِرَبِّ الْفَلَقِ } وَ { أَعُوذُ بِرَبِّ النَّاسِ } وَيَقُولُ " يَا عُقْبَةُ تَعَوَّذْ بِهِمَا فَمَا تَعَوَّذَ مُتَعَوِّذٌ بِمِثْلِهِمَا " . قَالَ وَسَمِعْتُهُ يَؤُمُّنَا بِهِمَا فِي الصَّلاَةِ .
Narrated Uqbah ibn Amir: White I was travelling with the Messenger of Allah (ﷺ) between al-Juhfah and al-Abwa', a wind and intense darkness enveloped us, whereupon the Messenger of Allah (ﷺ) began to seek refuge in Allah, reciting: "I seek refuge in the Lord of the dawn," and "I seek refuge in the Lord of men." He then said: Uqbah, use them when seeking refuge in Allah, for no one can use anything to compare with them for the purpose. Uqbah added: I heard him reciting them when he led the people in prayer.
