وَحَدَّثَنِي مَالِكٌ، عَنْ عَمْرِو بْنِ يَحْيَى الْمَازِنِيِّ، عَنْ أَبِيهِ، أَنَّهُ قَالَ كَانَ فِي حَائِطِ جَدِّهِ رَبِيعٌ لِعَبْدِ الرَّحْمَنِ بْنِ عَوْفٍ فَأَرَادَ عَبْدُ الرَّحْمَنِ بْنُ عَوْفٍ أَنْ يُحَوِّلَهُ إِلَى نَاحِيَةٍ مِنَ الْحَائِطِ هِيَ أَقْرَبُ إِلَى أَرْضِهِ فَمَنَعَهُ صَاحِبُ الْحَائِطِ فَكَلَّمَ عَبْدُ الرَّحْمَنِ بْنُ عَوْفٍ عُمَرَ بْنَ الْخَطَّابِ فِي ذَلِكَ فَقَضَى لِعَبْدِ الرَّحْمَنِ بْنِ عَوْفٍ بِتَحْوِيلِهِ ‏.‏
