Narrated `Aisha:
حَدَّثَنَا عُثْمَانُ بْنُ أَبِي شَيْبَةَ ، حَدَّثَنَا عَبْدَةُ ، عَنْ هِشَامٍ ، عَنْ أَبِيهِ ، عَنْ عَائِشَةَ ـ رضى الله عنها ـ قَالَتْ سَمِعَ النَّبِيُّ صلى الله عليه وسلم رَجُلاً يَقْرَأُ فِي الْمَسْجِدِ فَقَالَ " رَحِمَهُ اللَّهُ، لَقَدْ أَذْكَرَنِي كَذَا وَكَذَا آيَةً أَسْقَطْتُهَا فِي سُورَةِ كَذَا وَكَذَا " .
The Prophet (ﷺ) heard a man reciting (the Qur'an) in the mosque. He said," May Allah bestow His Mercy on him, as he made me remember such and-such Verse which I had missed in such-and-such Sura."
