عَنْ عُقْبَةَ بْنِ عَامِرٍ رَضِيَ اللَّهُ عَنْهُ قَالَ بَيْنَا أَنَا أَقُودُ بِرَسُولِ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ فِي نَقَبٍ مِنْ تِلْكَ النِّقَابِ إِذْ قَالَ لِي يَا عُقْبَةَ أَلَا تَرْكَبُ قَالَ فَأَجْلَلْتُ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ أَنْ أَرْكَبَ مَرْكَبَهُ ثُمَّ قَالَ يَا عُقَيْبُ أَلَا تَرْكَبُ قَالَ فَأَشْفَقْتُ أَنْ تَكُونَ مَعْصِيَةً قَالَ فَنَزَلَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ وَرَكِبْتُ هُنَيَّةً ثُمَّ رَكِبَ ثُمَّ قَالَ يَا عُقَيْبُ أَلَا أُعَلِّمُكَ سُورَتَيْنِ مِنْ خَيْرِ سُورَتَيْنِ قَرَأَ بِهِمَا النَّاسُ قَالَ قُلْتُ بَلَى يَا رَسُولَ اللَّهِ قَالَ فَأَقْرَأَنِي {قُلْ أَعُوذُ بِرَبِّ الْفَلَقِ} [الفلق: 1] وَ{قُلْ أَعُوذُ بِرَبِّ النَّاسِ} [الناس: 1] ثُمَّ أُقِيمَتِ الصَّلَاةُ فَتَقَدَّمَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ فَقَرَأَ بِهِمَا ثُمَّ مَرَّ بِي قَالَ كَيْفَ رَأَيْتَ يَا عُقَيْبُ اقْرَأْ بِهِمَا كُلَّمَا نِمْتَ وَكُلَّمَا قُمْتَ قَالَ أَبُو عَبْدِ الرَّحْمَنِ هُوَ عُقْبَةُ بْنُ عَامِرِ بْنِ عَابِسٍ وَقَالَ ابْنُ عَبْسٍ الْجُهَنِيُّ
Narrated by Sayyiduna Uqbah bin Amir (may Allah be pleased with him), he says: Once I was leading the mount of the Noble Prophet (peace and blessings be upon him) along a path passing through a mountain. Suddenly, the Prophet (peace and blessings be upon him) said to me: "O Uqbah! Why don't you ride?" I said nothing; in fact, out of reverence for the grandeur of the Prophet (peace and blessings be upon him), I did not wish to ride. But the Prophet (peace and blessings be upon him) again said: "O Uqayb! Why don't you ride?" Now I became afraid that this might be considered disobedience, so the Prophet (peace and blessings be upon him) dismounted and I rode for a short while. Then the Prophet (peace and blessings be upon him) mounted again and said: "O Uqayb! Shall I not teach you the two best Surahs which people recite?" I said: "Yes, absolutely, O Messenger of Allah!" So the Prophet (peace and blessings be upon him) taught me Surah Al-Falaq and Surah An-Naas. Meanwhile, the Iqamah for prayer was called, and the Noble Prophet (peace and blessings be upon him) advanced and recited these two Surahs in that prayer. Then he passed by me and said: "O Uqayb! How did you find (the excellence of these two Surahs, as I have recited them in prayer)?" Whenever you go to sleep and whenever you wake up, recite these Surahs.
