أَخْبَرَنَا مُحَمَّدُ بْنُ مَعْمَرٍ، قَالَ حَدَّثَنَا أَبُو عَامِرٍ، قَالَ حَدَّثَنَا شُعْبَةُ، عَنْ سَعْدٍ، - يَعْنِي ابْنَ إِبْرَاهِيمَ - عَنْ عُرْوَةَ، عَنْ بَشِيرٍ، أَنَّهُ نَحَلَ ابْنَهُ غُلاَمًا فَأَتَى النَّبِيَّ صلى الله عليه وسلم فَأَرَادَ أَنْ يُشْهِدَ النَّبِيَّ صلى الله عليه وسلم فَقَالَ ‏"‏ أَكُلَّ وَلَدِكَ نَحَلْتَهُ مِثْلَ ذَا ‏"‏ ‏.‏ قَالَ لاَ ‏.‏ قَالَ ‏"‏ فَارْدُدْهُ ‏"‏ ‏.‏
