It is narrated from Sayyiduna Anas bin Malik (may Allah be pleased with him) that he said: We offered the Asr prayer with the Messenger of Allah (peace and blessings be upon him). When he finished the prayer, a man from the tribe of Banu Salamah came and said: O Messenger of Allah, we want to slaughter a camel of ours, and we would like you to be present. He (peace and blessings be upon him) said: "Very well." So he set off, and we went along with him. (When we arrived) the camel had not yet been slaughtered. (After we arrived) the camel was slaughtered, then it was cut into pieces, then some of its meat was cooked, and we even ate it before the sun set.
