66/26. Chapter:
Forgetting the Qur'an. And can one say: “I forgot such and such a Verse?
وَقَوْلِ اللَّهِ تَعَالَى: {سَنُقْرِئُكَ فَلاَ تَنْسَى إِلاَّ مَا شَاءَ اللَّهُ}.
Sahih Bukhari
حَدَّثَنَا أَحْمَدُ بْنُ أَبِي رَجَاءٍ، حَدَّثَنَا أَبُو أُسَامَةَ، عَنْ هِشَامِ بْنِ عُرْوَةَ، عَنْ أَبِيهِ، عَنْ عَائِشَةَ، قَالَتْ سَمِعَ رَسُولُ اللَّهِ صلى الله عليه وسلم رَجُلاً يَقْرَأُ فِي سُورَةٍ بِاللَّيْلِ فَقَالَ " يَرْحَمُهُ اللَّهُ لَقَدْ أَذْكَرَنِي كَذَا وَكَذَا آيَةً كُنْتُ أُنْسِيتُهَا مِنْ سُورَةِ كَذَا وَكَذَا ".
Narrated Aisha: Allah's Messenger (ﷺ) heard a man reciting the Qur'an at night, and said, "May Allah bestow His Mercy on him, as he has reminded me of such-and-such Verses of such-and-such Suras, which I was caused to forget."
