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 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.
