صحيح مسلم

Anas b. Malik reported: The Messenger of Allah (ﷺ) led us in the afternoon prayer. When he completed it, a person from Bani Salama came to him and said: Messenger of Allah, we intend to slaughter our came and we are desirous that you should also be present there (on this occasion). He (the Holy Prophet) said: Yes. He (the person) went and we also went along with him and we found that the camel had not been slaughtered yet. Then it was slaughtered, and it was cut into pieces and then some of those were cooked, and then we ate (them) before the setting of the sun. This hadith has also been narrated by another chain of transmitters.
