Sahih Bukhari

Narrated Abu Qatada:I was with the Prophet (on a journey) between Mecca and Medina, and all of them, (i.e. the Prophet (ﷺ) and his companions) were in the state of Ihram, while I was not in that state. I was riding my horse and I used to be fond of ascending mountains. So while I was doing so I noticed that the people were looking at something. I went to see what it was, and behold it was an onager. I asked my companions, ""What is that?"" They said, ""We do not know."" I said, ""It is an onager.' They said, ""It is what you have seen."" I had left my whip, so I said to them, ""Hand to me my whip."" They said, ""We will not help you in that (in hunting the onager)."" I got down, took my whip and chased the animal (on my horse) and did not stop till I killed it. I went to them and said, ""Come on, carry it!"" But they said, ""We will not even touch it."" At last I alone carried it and brought it to them. Some of them ate of it and some refused to eat of it. I said (to them), ""I will ask the Prophet (ﷺ) about it (on your behalf)."" When I met the Prophet, I told him the whole story. He said to me, ""Has anything of it been left with you?"" I said, ""Yes."" He said, ""Eat, for it is a meal Allah has offered to you
