حَدَّثَنَا النُّفَيْلِيُّ، حَدَّثَنَا مُحَمَّدُ بْنُ سَلَمَةَ، عَنْ أَبِي عَبْدِ الرَّحِيمِ، - قَالَ أَبُو دَاوُدَ أَبُو عَبْدِ الرَّحِيمِ خَالِدُ بْنُ أَبِي يَزِيدَ خَالُ مُحَمَّدِ بْنِ سَلَمَةَ رَوَى عَنْهُ، حَجَّاجُ بْنُ مُحَمَّدٍ - عَنْ جَهْمِ بْنِ الْجَارُودِ، عَنْ سَالِمِ بْنِ عَبْدِ اللَّهِ، عَنْ أَبِيهِ، قَالَ أَهْدَى عُمَرُ بْنُ الْخَطَّابِ نَجِيبًا فَأُعْطِيَ بِهَا ثَلاَثَمِائَةِ دِينَارٍ فَأَتَى النَّبِيَّ صلى الله عليه وسلم فَقَالَ يَا رَسُولَ اللَّهِ إِنِّي أَهْدَيْتُ نَجِيبًا فَأُعْطِيتُ بِهَا ثَلاَثَمِائَةِ دِينَارٍ أَفَأَبِيعُهَا وَأَشْتَرِي بِثَمَنِهَا بُدْنًا قَالَ ‏"‏ لاَ انْحَرْهَا إِيَّاهَا ‏"‏ ‏.‏ قَالَ أَبُو دَاوُدَ هَذَا لأَنَّهُ كَانَ أَشْعَرَهَا ‏.‏

Narrated Abdullah ibn Umar: Umar ibn al-Khattab named a bukhti camel for sacrifice (at hajj). He was offered three hundred dinars for it (as its price). He came to the Prophet (PBUH) and said: Messenger of Allah, I named a bukhti camel for sacrifice and I was offered for it three hundred dinars. May I sell it and purchase another one for its price? No, sacrifice it. Abu Dawud said: This was due to the fact that 'Umar had made an incision in hump. Translation Not Available
