AbuMajidah said:

I cut the ear of a boy, or he cut my ear (the narrator is doubtful). AbuBakr then came to us to perform hajj and we got together with him. But he referred us to Umar ibn al-Khattab. Umar (ibn al-Khattab) said: This reached the extent of retaliation. Call a cupper to me so that he may retaliate. When the cupper was called, he (Umar) said: I heard the Messenger of Allah ﷺ say: I gave a boy to my maternal aunt, and I hope that she will be blessed in respect of him. I said to her: Do not entrust him to a supper, nor to a goldsmith, nor to a butcher.

Abu Dawud said: This tradition has also been transmitted by 'Abd al-A'la from Ibn Ishaq who said: Abu Majidah is a man of Banu Sahm narrating from 'Umar b. al-Khattab.

حَدَّثَنَا مُوسَى بْنُ إِسْمَاعِيلَ، حَدَّثَنَا حَمَّادُ بْنُ سَلَمَةَ، أَخْبَرَنَا مُحَمَّدُ بْنُ إِسْحَاقَ، عَنِ الْعَلاَءِ بْنِ عَبْدِ الرَّحْمَنِ، عَنْ أَبِي مَاجِدَةَ، قَالَ قَطَعْتُ مِنْ أُذُنِ غُلاَمٍ - أَوْ قُطِعَ مِنْ أُذُنِي - فَقَدِمَ عَلَيْنَا أَبُو بَكْرٍ حَاجًّا فَاجْتَمَعْنَا إِلَيْهِ فَرَفَعَنَا إِلَى عُمَرَ بْنِ الْخَطَّابِ فَقَالَ عُمَرُ إِنَّ هَذَا قَدْ بَلَغَ الْقِصَاصَ ادْعُوا لِي حَجَّامًا لِيَقْتَصَّ مِنْهُ فَلَمَّا دُعِيَ الْحَجَّامُ قَالَ سَمِعْتُ رَسُولَ اللَّهِ ﷺ يَقُولُ " إِنِّي وَهَبْتُ لِخَالَتِي غُلاَمًا وَأَنَا أَرْجُو أَنْ يُبَارَكَ لَهَا فِيهِ فَقُلْتُ لَهَا لاَ تُسَلِّمِيهِ حَجَّامًا وَلاَ صَائِغًا وَلاَ قَصَّابًا " . قَالَ أَبُو دَاوُدَ رَوَى عَبْدُ الأَعْلَى عَنِ ابْنِ إِسْحَاقَ قَالَ ابْنُ مَاجِدَةَ رَجُلٌ مِنْ بَنِي سَهْمٍ عَنْ عُمَرَ بْنِ الْخَطَّابِ .
