It was narrated that 'Uqbah bin 'Amir said:

"The Prophet ﷺ was given a gray mule which he rode, and 'Uqbah led it. The Messenger of Allah ﷺ said to 'Uqbah: 'Recite.' He said: 'What should I recite, O Messenger of Allah?' He said: 'Recite: 'Say: I seek refuge with (Allah) the Lord of the daybreak, from the evil of what He has created.' And he repeated it until I had learned it."

أَخْبَرَنِي عَمْرُو بْنُ عُثْمَانَ، قَالَ حَدَّثَنَا بَقِيَّةُ، قَالَ حَدَّثَنَا بَحِيرُ بْنُ سَعْدٍ، عَنْ خَالِدِ بْنِ مَعْدَانَ، عَنْ جُبَيْرِ بْنِ نُفَيْرٍ، عَنْ عُقْبَةَ بْنِ عَامِرٍ، قَالَ أُهْدِيَتْ لِلنَّبِيِّ ﷺ بَغْلَةٌ شَهْبَاءُ فَرَكِبَهَا وَأَخَذَ عُقْبَةُ يَقُودُهَا بِهِ فَقَالَ رَسُولُ اللَّهِ ﷺ لِعُقْبَةَ " اقْرَأْ " . قَالَ وَمَا أَقْرَأُ يَا رَسُولَ اللَّهِ قَالَ " اقْرَأْ { قُلْ أَعُوذُ بِرَبِّ الْفَلَقِ * مِنْ شَرِّ مَا خَلَقَ } " . فَأَعَادَهَا عَلَىَّ حَتَّى قَرَأْتُهَا فَعَرَفَ أَنِّي لَمْ أَفْرَحْ بِهَا جِدًّا قَالَ " لَعَلَّكَ تَهَاوَنْتَ بِهَا " . فَمَا قُمْتُ يَعْنِي بِمِثْلِهَا .
