Messenger of Allah 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."
سَمِعَ رَسُولُ اللَّهِ ﷺ رَجُلاً يَقْرَأُ فِي سُورَةٍ بِاللَّيْلِ فَقَالَ يَرْحَمُهُ اللَّهُ لَقَدْ أَذْكَرَنِي كَذَا وَكَذَا آيَةً كُنْتُ أُنْسِيتُهَا مِنْ سُورَةِ كَذَا وَكَذَا
