أَنَّ عَبْدَ اللَّهِ بْنَ عُمَرَ كَانَ يَقُولُ الْمُكَاتَبُ عَبْدٌ مَا بَقِيَ عَلَيْهِ مِنْ كِتَابَتِهِ شَىْءٌ

البيهقي:٢١٦٤٢ – أَخْبَرَنَا أَبُو عَبْدِ اللهِ الْحَافِظُ وَأَبُو سَعِيدِ بْنُ أَبِي عَمْرٍو قَالَ ثنا أَبُو الْعَبَّاسِ مُحَمَّدُ بْنُ يَعْقُوبَ ثنا يَحْيَى بْنُ أَبِي طَالِبٍ أنبأ يَزِيدُ بْنُ هَارُونَ أنبأ سُفْيَانُ الثَّوْرِيُّ عَنْ عَبْدِ اللهِ بْنِ أَبِي نَجِيحٍ عَنْ مُجَاهِدٍ قَالَ

كَانَ زَيْدٌ يَقُولُ الْمُكَاتَبُ عَبْدٌ مَا بَقِيَ عَلَيْهِ شَيْءٌ مِنْ مُكَاتَبَتِهِ وَكَانَ جَابِرُ بْنُ عَبْدِ اللهِ يَقُولُ شُرُوطُهُمْ جَائِزَةٌ بَيْنَهُمْ
