أَخْبَرَنَا شُعَيْبُ بْنُ يُوسُفَ، قَالَ حَدَّثَنَا عَبْدُ الرَّحْمَنِ، عَنْ مُعَاوِيَةَ بْنِ صَالِحٍ، عَنْ عَبْدِ اللَّهِ بْنِ أَبِي قَيْسٍ، قَالَ سَأَلْتُ عَائِشَةَ كَيْفَ كَانَتْ قِرَاءَةُ رَسُولِ اللَّهِ صلى الله عليه وسلم بِاللَّيْلِ يَجْهَرُ أَمْ يُسِرُّ قَالَتْ كُلُّ ذَلِكَ قَدْ كَانَ يَفْعَلُ رُبَّمَا جَهَرَ وَرُبَّمَا أَسَرَّ ‏.‏
