البيهقي:٥٦١٠ – أَخْبَرَنَا أَبُو حَازِمٍ الْعَبْدَوِيُّ أنبأ أَبُو أَحْمَدَ الْحَافِظُ أنبأ أَبُو عُثْمَانَ سَعِيدُ بْنُ عَبْدِ الْعَزِيزِ الْحَلَبِيُّ ثنا أَبُو نُعَيْمٍ الْحَلَبِيُّ يَعْنِي عُبَيْدَ بْنَ هِشَامٍ ثنا أَبُو الْمَلِيحِ يَعْنِي الرَّقِّيَّ قَالَ

أَتَانَا كِتَابُ عُمَرَ بْنِ عَبْدِ الْعَزِيزِ إِذَا بَلَغَ أَهْلُ الْقَرْيَةِ أَرْبَعِينَ رَجُلًا فَلْيُجَمِّعُوا
