عَنْ عُقْبَةَ بْنِ عَامِرٍ رَضِيَ اللَّهُ عَنْهُ لَقِيَنِي رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ فَابْتَدَأَنِي فَأَخَذَ بِيَدِي فَقَالَ يَا عُقْبَةَ بْنَ عَامِرٍ أَلَا أُعَلِّمُكَ خَيْرَ ثَلَاثِ سُوَرٍ أُنْزِلَتْ فِي التَّوْرَاةِ وَالْإِنْجِيلِ وَالزَّبُورِ وَالْفُرْقَانِ الْعَظِيمِ قَالَ قُلْتُ بَلَى جَعَلَنِيَ اللَّهُ فِدَاكَ قَالَ فَأَقْرَأَنِي {قُلْ هُوَ اللَّهُ أَحَدٌ} [الإخلاص: 1] وَ{قُلْ أَعُوذُ بِرَبِّ الْفَلَقِ} [الفلق: 1] وَ{قُلْ أَعُوذُ بِرَبِّ النَّاسِ} [الناس: 1] ثُمَّ قَالَ يَا عُقْبَةَ لَا تَنْسَاهُنَّ وَلَا تَبِتْ لَيْلَةً حَتَّى تَقْرَأَهُنَّ قَالَ فَمَا نَسِيتُهُنَّ مُنْذُ قَالَ لَا تَنْسَاهُنَّ وَمَا بِتُّ لَيْلَةً قَطُّ حَتَّى أَقْرَأَهُنَّ
It is narrated from Sayyiduna Uqbah bin Amir (may Allah be pleased with him), he says: The Noble Prophet (peace and blessings be upon him) met me, he (peace and blessings be upon him) initiated the greeting of peace and said: O Uqbah bin Amir! Shall I not teach you the best three Surahs that were revealed in the Torah, the Gospel, the Psalms, and the Noble Qur’an? I said: May Allah sacrifice me for you, certainly tell me. Then he (peace and blessings be upon him) taught me Surah Ikhlas, Surah Falaq, and Surah Nas and said: O Uqbah! Do not forget them and do not spend any night except that you recite them in it. Since the time he (peace and blessings be upon him) advised me not to forget them, I have not forgotten them, nor have I spent any night except that I have recited them in it.
