"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.'" (Using translation from Nasāʾī 953)  

اتَّبَعْتُ رَسُولَ اللهِ ﷺ وَهُوَ رَاكِبٌ فَوَضَعْتُ يَدَيَّ عَلَى قَدَمِهِ فَقُلْتُ أَقْرِئْنِي سُورَةَ هُودٍ أَوْ سُورَةَ يُوسُفَ فَقَالَ «لَنْ تَقْرَأَ شَيْئًا أَبْلَغَ عِنْدَ اللهِ مِنْ قُلْ أَعُوذُ بِرَبِّ الْفَلَقِ»  

[Machine] The Messenger of Allah ﷺ said, "There are verses that were revealed to me tonight that have never been seen before. Say, 'I seek refuge in the Lord of daybreak,' and say, 'I seek refuge in the Lord of mankind.'"  

قَالَ رَسُولُ اللهِ ﷺ آيَاتٌ أُنْزِلَتْ عَلَيَّ اللَّيْلَةَ لَمْ يُرَ مِثْلَهُنَّ قَطُّ قُلْ أَعُوذُ بِرَبِّ الْفَلَقِ وَقُلْ أَعُوذُ بِرَبِّ النَّاسِ
