"I came to the Messenger of Allah [SAW] while he was riding, and I put my hand on his foot and said: 'Teach me Surah Hud, teach me Surah Yusuf. He said: 'You will never recite anything more precious before Allah, the Mighty and Sublime, than: 'Say: I seek refuge with (Allah) the Lord of the daybreak.'"  

أَتَيْتُ رَسُولَ اللَّهِ ﷺ وَهُوَ رَاكِبٌ فَوَضَعْتُ يَدِي عَلَى قَدَمِهِ فَقُلْتُ أَقْرِئْنِي سُورَةَ هُودٍ أَقْرِئْنِي سُورَةَ يُوسُفَ فَقَالَ لَنْ تَقْرَأَ شَيْئًا أَبْلَغَ عِنْدَ اللَّهِ ﷻ مِنْ { قُلْ أَعُوذُ بِرَبِّ الْفَلَقِ }  

[Machine] I said, "O Messenger of Allah, shall I recite from Surah Yusuf and Surah Hud?" He replied, "O 'Uqbah, recite! Seek refuge with the Lord of daybreak, for you will not recite a surah that is more beloved to Allah and more comprehensive in His sight than it. If you are able to not miss it, then do so."  

قُلْتُ يَا رَسُولَ اللَّهِ أَقْرَأُ مِنْ سُورَةِ يُوسُفَ وَسُورَةِ هُودٍ قَالَ «يَا عُقْبَةُ اقْرَأْ بِأَعُوذُ بِرَبِّ الْفَلَقِ فَإِنَّكَ لَنْ تَقْرَأَ بِسُورَةٍ أَحَبَّ إِلَى اللَّهِ وَأَبْلَغَ عِنْدَهُ مِنْهَا فَإِنِ اسْتَطَعْتَ أَنْ لَا تَفُوتَكَ فَافْعَلْ»  

[Machine] "He heard Uqbah bin 'Amir say, 'I followed the Messenger of Allah ﷺ while he was riding, so I placed my hand on his foot and said, 'O Messenger of Allah, teach me either a Surah from Surah Hud or a Surah from Surah Yusuf.' The Messenger of Allah ﷺ said, 'O Uqbah bin 'Amir, you will not recite a Surah more beloved to Allah or more significant to Him than "Say, 'I seek refuge in the Lord of daybreak'" (Surah Al-Falaq). If you can make sure it is not missed in your prayer, then do so.'"  

أَنَّهُ سَمِعَ عُقْبَةَ بْنَ عَامِرٍ يَقُولُ تَبِعْتُ رَسُولَ اللَّهِ ﷺ وَهُوَ رَاكِبٌ فَجَعَلْتُ يَدِي عَلَى قَدَمِهِ فَقُلْتُ يَا رَسُولَ اللَّهِ أَقْرِئْنِي إِمَّا مِنْ سُورَةِ هُودٍ وَإِمَّا مِنْ سُورَةِ يُوسُفَ فَقَالَ رَسُولُ اللَّهِ ﷺ «يَا عُقْبَةُ بْنَ عَامِرٍ إِنَّكَ لَنْ تَقْرَأَ سُورَةً أَحَبَّ إِلَى اللَّهِ وَلَا أَبْلَغَ عِنْدَهُ مِنْ أَنْ تَقْرَأَ قُلْ أَعُوذُ بِرَبِّ الْفَلَقِ فَإِنِ اسْتَطَعْتَ أَنْ لَا تَفُوتَكَ فِي صَلَاةٍ فَافْعَلْ»  

[Machine] I heard the Messenger of Allah ﷺ once while he was riding, so I placed my hand on his foot and said, "O Messenger of Allah, recite for me a verse from Surah Hud or from Surah Yusuf." The Messenger of Allah ﷺ said, "O Uqbah ibn Amir, you will not recite a surah that is more beloved to Allah and more reach in virtue than reciting 'Say: I seek refuge in the Lord of Daybreak,' if you can ensure that you do not miss it in your prayers, then do so."  

سَمِعْتُ رَسُولَ اللهِ ﷺ يَوْمًا وَهُوَ رَاكِبٌ فَوَضَعْتُ يَدِي عَلَى قَدَمِهِ فَقُلْتُ يَا رَسُولَ اللهِ أَقْرِئْنِي مِنْ سُورَةِ هُودٍ وَإِمَّا مِنْ سُورَةِ يُوسُفَ فَقَالَ رَسُولُ اللهِ ﷺ «يَا عُقْبَةُ بْنَ عَامِرٍ إِنَّكَ لَنْ تَقْرَأَ بِسُورَةٍ أَحَبَّ إِلَى اللهِ وَأَبْلَغَ عِنْدَهُ مِنْ أَنْ تَقْرَأَ بِقُلْ أَعُوذُ بِرَبِّ الْفَلَقِ فَإِنِ اسْتَطَعْتَ أَنْ لَا تَفُوتَكَ فِي صَلَاةٍ فَافْعَلْ»  

"يَا عُقْبَةُ بْنَ عَامِرٍ: إِنَّكَ لَنْ تَقْرَأَ بِسُورَة أحَبَّ إِلى الله، وَلاَ أبْلَغَ عِنْدَهُ مِنْ أنْ تَقْرَأَ " {قُلْ أَعُوذُ بِرَبِّ الْفَلَقِ}، فَإِنِ اسْتَطَعْتَ أنْ لاَ تَفُوتَكَ فِى صَلاَةٍ فَافْعَلْ".
