وَحَدَّثَنَا أَبُو بَكْرِ بْنُ أَبِي شَيْبَةَ، قَالَ وَجَدْتُ فِي كِتَابِي عَنْ أَبِي أُسَامَةَ، عَنْ هِشَامٍ، عَنْ أَبِيهِ، عَنْ عَائِشَةَ، قَالَتْ إِنْ كَانَ رَسُولُ اللَّهِ صلى الله عليه وسلم لَيَتَفَقَّدُ يَقُولُ " أَيْنَ أَنَا الْيَوْمَ أَيْنَ أَنَا غَدًا " . اسْتِبْطَاءً لِيَوْمِ عَائِشَةَ . قَالَتْ فَلَمَّا كَانَ يَوْمِي قَبَضَهُ اللَّهُ بَيْنَ سَحْرِي وَنَحْرِي .
