Sahih Muslim , Book 4, Hadith 1720 (USC-MSA) ⓘ
'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 " .
