Sahih Muslim , Hadith 788

'A'isha reported that the Messenger of Allah heard a person reciting the Qur'an at night. Upon this he said: May Allah show mercy to him; he has reminded me of such and such a verse which I had missed in such and such a surah.

حَدَّثَنَا أَبُو بَكْرِ بْنُ أَبِي شَيْبَةَ، وَأَبُو كُرَيْبٍ قَالاَ حَدَّثَنَا أَبُو أُسَامَةَ، عَنْ هِشَامٍ، عَنْ أَبِيهِ، عَنْ عَائِشَةَ، أَنَّ النَّبِيَّ صلى الله عليه وسلم سَمِعَ رَجُلاً يَقْرَأُ مِنَ اللَّيْلِ فَقَالَ ‏ "‏ يَرْحَمُهُ اللَّهُ لَقَدْ أَذْكَرَنِي كَذَا وَكَذَا آيَةً كُنْتُ أَسْقَطْتُهَا مِنْ سُورَةِ كَذَا وَكَذَا ‏" ‏ ‏.‏

'A'isha reported that the Messenger of Allah listened to the recitation of the Qur'an by a man in the mosque. Thereupon he said: May Allah have mercy upon him; be reminded me of the verse which I had been made to forget.

وَحَدَّثَنَا ابْنُ نُمَيْرٍ، حَدَّثَنَا عَبْدَةُ، وَأَبُو مُعَاوِيَةَ عَنْ هِشَامٍ، عَنْ أَبِيهِ، عَنْ عَائِشَةَ، قَالَتْ كَانَ النَّبِيُّ صلى الله عليه وسلم يَسْتَمِعُ قِرَاءَةَ رَجُلٍ فِي الْمَسْجِدِ ‏.‏ فَقَالَ ‏ "‏ رَحِمَهُ اللَّهُ لَقَدْ أَذْكَرَنِي آيَةً كُنْتُ أُنْسِيتُهَا ‏" ‏ ‏.‏
