البيهقي:١٣٥٤٢ – أَخْبَرَنَا أَبُو نَصْرٍ عُمَرُ بْنُ عَبْدِ الْعَزِيزِ بْنِ عُمَرَ بْنِ قَتَادَةَ الْأَنْصَارِيُّ أنبأ أَبُو مَنْصُورٍ الْعَبَّاسُ بْنُ الْفَضْلِ النَّضْرَوِيّ ثنا أَحْمَدُ بْنُ نَجْدَةَ ثنا سَعِيدُ بْنُ مَنْصُورٍ ثنا عِيسَى بْنُ يُونُسَ ثنا هِشَامُ بْنُ الْغَازِ بْنِ رَبِيعَةَ الْجُرَشِيُّ عَنْ عُبَادَةَ بْنِ نُسَيٍّ الْكِنْدِيِّ قَالَ كَتَبَ عُمَرُ بْنُ الْخَطَّابِ ؓ إِلَى أَبِي عُبَيْدَةَ بْنِ الْجَرَّاحِ ؓ أَمَّا بَعْدُ فَإِنَّهُ بَلَغَنِي
