البيهقي:١٠٢٧٢ – وَأَخْبَرَنَا أَبُو أَحْمَدَ الْعَدْلُ أنا أَبُو بَكْرِ بْنُ جَعْفَرٍ الْمُزَكِّي ثنا مُحَمَّدُ بْنُ إِبْرَاهِيمَ ثنا ابْنُ بُكَيْرٍ ثنا مَالِكٌ عَنْ عَبْدِ اللهِ بْنِ دِينَارٍ أَنَّهُ قَالَ رَأَيْتُ

عَبْدَ اللهِ بْنَ عُمَرَ يَقِفُ عَلَى قَبْرِ النَّبِيِّ ﷺ ثُمَّ يُسَلِّمُ عَلَى النَّبِيِّ ﷺ وَيَدْعُو ثُمَّ يَدْعُو لِأَبِي بَكْرٍ وَعُمَرَ ؓ
