حَدَّثَنَا عَمْرُو بْنُ عُثْمَانَ، حَدَّثَنَا أَبُو الْمُغِيرَةِ، حَدَّثَنِي صَفْوَانُ، عَنْ شُرَيْحِ بْنِ عُبَيْدٍ، عَنْ سَعْدِ بْنِ أَبِي وَقَّاصٍ، أَنَّ النَّبِيَّ صلى الله عليه وسلم قَالَ ‏ "‏ إِنِّي لأَرْجُو أَنْ لاَ تُعْجِزَ أُمَّتِي عِنْدَ رَبِّهَا أَنْ يُؤَخِّرَهُمْ نِصْفَ يَوْمٍ ‏" ‏ ‏.‏ قِيلَ لِسَعْدٍ وَكَمْ نِصْفُ يَوْمٍ قَالَ خَمْسُمِائَةِ سَنَةٍ ‏.‏
