حَدَّثَنَا أَبُو بَكْرِ بْنُ أَبِي شَيْبَةَ، حَدَّثَنَا مُحَمَّدُ بْنُ عُبَيْدٍ، حَدَّثَنَا يَزِيدُ بْنُ كَيْسَانَ، عَنْ أَبِي حَازِمٍ، عَنْ أَبِي هُرَيْرَةَ، قَالَ زَارَ النَّبِيُّ ـ صلى الله عليه وسلم ـ قَبْرَ أُمِّهِ فَبَكَى وَأَبْكَى مَنْ حَوْلَهُ فَقَالَ: ‏"‏ اسْتَأْذَنْتُ رَبِّي فِي أَنْ أَسْتَغْفِرَ لَهَا فَلَمْ يَأْذَنْ لِي وَاسْتَأْذَنْتُ رَبِّي فِي أَنْ أَزُورَ قَبْرَهَا فَأَذِنَ لِي فَزُورُوا الْقُبُورَ فَإِنَّهَا تُذَكِّرُكُمُ الْمَوْتَ ‏"‏ ‏.‏
