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 ﷺ 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.

أَهْدَى عُمَرُ بْنُ الْخَطَّابِ نَجِيبًا فَأُعْطِيَ بِهَا ثَلاَثَمِائَةِ دِينَارٍ فَأَتَى النَّبِيَّ ﷺ فَقَالَ يَا رَسُولَ اللَّهِ إِنِّي أَهْدَيْتُ نَجِيبًا فَأُعْطِيتُ بِهَا ثَلاَثَمِائَةِ دِينَارٍ أَفَأَبِيعُهَا وَأَشْتَرِي بِثَمَنِهَا بُدْنًا قَالَ لاَ انْحَرْهَا إِيَّاهَا

[Machine] Umar ibn Al-Khattab presented a camel as a gift and was given three hundred dinars for it. He then went to the Messenger of Allah ﷺ and said, "O Messenger of Allah, I have been given three hundred dinars for the camel that I presented as a gift. Should I slaughter it or should I buy a different camel with its price?" The Prophet ﷺ replied, "No, rather slaughter it."

أَهْدَى عُمَرُ بْنُ الْخَطَّابِ بُخْتِيَّةً أُعْطِيَ بِهَا ثَلَاثَ مِائَةِ دِينَارٍ فَأَتَى رَسُولَ اللهِ ﷺ فَقَالَ يَا رَسُولَ اللهِ أَهْدَيْتُ بُخْتِيَّةً لِي أُعْطِيتُ بِهَا ثَلَاثَ مِائَةِ دِينَارٍ فَأَنْحَرُهَا أَوْ أَشْتَرِي بِثَمَنِهَا بُدْنًا قَالَ لَا وَلَكِنِ انْحَرْهَا إِيَّاهَا

[Machine] Umar ibn al-Khattab presented a gift, and he was given three hundred dinars in return. He then went to the Prophet ﷺ and said, "O Messenger of Allah, I presented a gift and was given three hundred dinars in return. Should I sell it and buy a Buda?" or he said "badana" or he said "badanah." The Prophet replied, "No, but instead sacrifice it to Allah." Abu Dawud, Abu Abdur-Rahim, Khalid ibn Yazid, the nephew of Muhammad ibn Salamah, narrated from him.

أَهْدَى عُمَرُ بْنُ الْخَطَّابِ ؓ نَجِيبًا فَأُعْطَى بِهَا ثَلَاثَ مِائَةِ دِينَارٍ فَأَتَى النَّبِيَّ ﷺ فَقَالَ يَا رَسُولَ اللهِ إِنِّي أَهْدَيْتُ نَجِيبًا فَأُعْطِيتُ بِهَا ثَلَاثَ مِائَةِ دِينَارٍ فَأَبِيعُهَا وَأَشْتَرِي بِثَمَنِهَا بُدْنًا؟ أَوْ قَالَ بَدَنَةً أَوْ قَالَ بَدَنَةً الشَّكُّ مِنِّي قَالَ لَا وَلَكِنِ انْحَرْهَا إِيَّاهَا قَالَ أَبُو دَاوُدَ أَبُو عَبْدِ الرَّحِيمِ خَالِدُ بْنُ يَزِيدَ خَالُ مُحَمَّدِ بْنِ سَلَمَةَ رَوَى عَنْهُ حَجَّاجُ بْنُ مُحَمَّدٍ
