"While I was leading the Messenger of Allah [SAW] (on his mount) in one of these mountain passes, he said: 'Why don't you ride, O 'Uqbah?' I had too much respect for the Messenger of Allah [SAW] to ride the mount of the Messenger of Allah [SAW]. Then he said: 'Why don't you ride, O 'Uqbah?' I was worried that I might be disobeying him, so he got off, and I rode for a little while, then I got off and the Messenger of Allah [SAW] rode. Then he said: 'Shall I not teach you two of the best Surahs that the people recite?' And he taught me: 'Say: I seek refuge with (Allah) the Lord of the daybreak,' and 'Say: I seek refuge with (Allah) the Lord of mankind." Then the Iqamah was said and he went forward and recited them. Then he passed by me and said: 'What do you think, O 'Uqbah bin 'Amir? Recite them every time you go to sleep and get up.'" (Using translation from Nasāʾī 5437)
بَيْنَا أَنَا أَقُودُ بِرَسُولِ اللهِ ﷺ فِي نَقَبٍ مِنْ تِلْكَ النِّقَابِ إِذْ قَالَ لِي يَا عُقْبَ أَلَا تَرْكَبُ؟ قَالَ فَأَجْلَلْتُ رَسُولَ اللهِ ﷺ أَنْ أَرْكَبَ مَرْكَبَهُ ثُمَّ قَالَ يَا عُقْبُ أَلَا تَرْكَبُ؟ قَالَ فَأَشْفَقْتُ أَنْ تَكُونَ مَعْصِيَةً قَالَ فَنَزَلَ رَسُولُ اللهِ ﷺ وَرَكِبْتُ هُنَيَّةً ثُمَّ رَكِبَ ثُمَّ قَالَ يَا عُقْبُ أَلَا أُعَلِّمُكَ سُورَتَيْنِ مِنْ خَيْرِ سُورَتَيْنِ قَرَأَ بِهِمَا النَّاسُ؟ قَالَ قُلْتُ بَلَى يَا رَسُولَ اللهِ قَالَ فَأَقْرَأَنِي قُلْ أَعُوذُ بِرَبِّ الْفَلَقِ وَقُلْ أَعُوذُ بِرَبِّ النَّاسِ ثُمَّ أُقِيمَتِ الصَّلَاةُ فَتَقَدَّمَ رَسُولُ اللهِ ﷺ فَقَرَأَبِهِمَا ثُمَّ مَرَّ بِي قَالَ كَيْفَ رَأَيْتَ يَا عُقْبُ؟ اقْرَأْ بِهِمَا كُلَّمَا نِمْتَ وَكُلَّمَا قُمْتَ
