"I followed the Messenger of Allah ﷺ when he was riding, and I placed my hand on his foot and said : O Messenger of Allah, teach me Surah Hud and Surah Yusuf. He said: 'You will never recite anything greater before Allah than: "Say: I seek refuge with (Allah), the Lord of the daybreak." And "Say: I seek refuge with (Allah) the Lord of mankind.'"  

اتَّبَعْتُ رَسُولَ اللَّهِ ﷺ وَهُوَ رَاكِبٌ فَوَضَعْتُ يَدِي عَلَى قَدَمِهِ فَقُلْتُ أَقْرِئْنِي يَا رَسُولَ اللَّهِ سُورَةَ هُودٍ وَسُورَةَ يُوسُفَ فَقَالَ لَنْ تَقْرَأَ شَيْئًا أَبْلَغَ عِنْدَ اللَّهِ مِنْ { قُلْ أَعُوذُ بِرَبِّ الْفَلَقِ } وَ { قُلْ أَعُوذُ بِرَبِّ النَّاسِ }  

The Messenger of Allah ﷺ said: 'Some verses were revealed to me tonight, the likes of which have never been seen: "Say: I seek refuge with (Allah), the Lord of the daybreak." [Surat al-Falaq:1] and "Say: I seek refuge with (Allah) the Lord of mankind." [Surat an-Naas:1]'  

قَالَ رَسُولُ اللَّهِ ﷺ آيَاتٌ أُنْزِلَتْ عَلَىَّ اللَّيْلَةَ لَمْ يُرَ مِثْلُهُنَّ قَطُّ { قُلْ أَعُوذُ بِرَبِّ الْفَلَقِ } وَ { قُلْ أَعُوذُ بِرَبِّ النَّاسِ }
