While we were besieging the castle of Khaibar, Somebody threw a skin full of fat and I went ahead to take it, but on looking behind, I saw the Prophet (ﷺ) and I felt shy in his presence (and did not take it).
Sahih al-Bukhari Book 72, Hadith 34
← Previous Hadith A group of people said to the Prophet, "Some people bring us meat and we do not know whether they have mentioned Allah's Name or not on slaughtering the animal." He said, "Mention Allah's Name on it and eat." Those people had embraced Islam recently.

Sahih al-Bukhari Book 72, Hadith 33 Next Hadith → I said, "O Allah's Messenger (ﷺ)! We are going to face the enemy tomorrow and we do not have knives." He said, "Hurry up (in killing the animal). If the killing tool causes blood to flow out, and if Allah's Name is mentioned, eat (of the slaughtered animal). But do not slaughter with a tooth or a nail. I will tell you why: As for the tooth, it is a bone; and as for the nail, it is the knife of Ethiopians." Then we got some camels and sheep as war booty, and one of those camels ran away, whereupon a man shot it with an arrow and stopped it. Allah's Messenger (ﷺ) said, "Of these camels there are some which are as wild as wild beasts, so if one of them (runs away and) makes you tired, treat it in this manner."
