The virtue of reciting al-Mu`awwidhatain (the two surahs seeking refuge with Allah)
Sahih Muslim
وَحَدَّثَنَا قُتَيْبَةُ بْنُ سَعِيدٍ، حَدَّثَنَا جَرِيرٌ، عَنْ بَيَانٍ، عَنْ قَيْسِ بْنِ أَبِي حَازِمٍ، عَنْ عُقْبَةَ بْنِ عَامِرٍ، قَالَ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم " أَلَمْ تَرَ آيَاتٍ أُنْزِلَتِ اللَّيْلَةَ لَمْ يُرَ مِثْلُهُنَّ قَطُّ { قُلْ أَعُوذُ بِرَبِّ الْفَلَقِ} وَ { قُلْ أَعُوذُ بِرَبِّ النَّاسِ} " .
'Uqba b. 'Amir reported Allah's Messenger (ﷺ) as saying: What wonderful verses have been sent down today. the like of which has never been seen! They are:" Say: I seek refuge with the Lord of the dawn," and" Say: I seek refuge with the Lord of men."
