‘Abdallāh b. ‘Amr told of a man coming to the Prophet (ﷺ) and asking him to teach him to recite. On being told to recite three of the <i>sūras</i> with <i>A. L. R</i> (Qur’ān, 10, 11, 12, 14, and 15) he replied, “I am old, my heart has difficulty in remem­bering, and my tongue is sluggish.” When told that in that case he should recite three with <i>Hā’ Mīm</i> (Qur’ān, 40 to 46) he gave the same reply and then asked God’s messenger to teach him to recite a comprehensive <i>sūra</i>. He taught him to recite “When is shaken” (Qur’ān, 99) up to the end, and the man said, “I swear by Him who has sent you with the truth that I shall never recite more than that.” Then when the man turned away God's messenger said twice, “The little man has come into a state of felicity.” Ahmad and Abū Dāwūd transmitted it.

وَعَن عَبْدِ اللَّهِ بْنِ عَمْرٍو قَالَ: أَتَى رَجُلٌ النَّبِيَّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ فَقَالَ أَقْرِئْنِي يَا رَسُولَ اللَّهِ فَقَالَ: " اقْرَأْ ثَلَاثًا مِنْ ذَوَاتِ (ألر) فَقَالَ: كَبُرَتْ سِنِّي وَاشْتَدَّ قَلْبِي وَغَلُظَ لِسَانِي قَالَ: " فَاقْرَأْ ثَلَاثًا مِنْ ذَوَاتِ (حم) فَقَالَ مِثْلَ مَقَالَتِهِ. قَالَ الرَّجُلُ: يَا رَسُولَ اللَّهِ أَقْرِئْنِي سُورَةً جَامِعَةً فَأَقْرَأَهُ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ (إِذَا زُلْزِلَتْ الأَرْض) حَتَّى فَرَغَ مِنْهَا فَقَالَ الرَّجُلُ: وَالَّذِي بَعَثَكَ بِالْحَقِّ لَا أَزِيد عَلَيْهَا أبدا ثمَّ أدبر الرَّجُلُ فَقَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ أَفْلَحَ الرُّوَيْجِلُ " مَرَّتَيْنِ. رَوَاهُ أَحْمَدُ وَأَبُو دَاوُدَ
