The Messenger of Allah [SAW] said to him: "O Ibn 'Abis, shall I not tell you of the best thing with which those who seek refuge with Allah may do so?" He said: "Yes, O Messenger of Allah." He said: "Say: I seek refuge with (Allah) the Lord of the daybreak.", "Say: I seek refuge with (Allah) the Lord of mankind." - these two Surahs." (Using translation from Nasāʾī 5432)
أَخْبَرَهُ أَنَّ النَّبِيَّ ﷺ قَالَ لَهُ «يَا ابْنَ عَابِسٍ أَلَا أَدُلُّكُ» أَوْ قَالَ «أَلَا أُخْبِرُكَ بِأَفْضَلِ مَا يَتَعَوَّذُ بِهِ الْمُتَعَوِّذُونَ؟» قَالَ بَلَى يَا رَسُولَ اللهِ قَالَ «قُلْ أَعُوذُ بِرَبِّ الْفَلَقِ وَقُلْ أَعُوذُ بِرَبِّ النَّاسِ هَاتَانِ السُّورَتَانِ»
