It is narrated from Sayyiduna Umar bin al-Khattab (may Allah be pleased with him) that he asked: "Which of you was present with the Messenger of Allah (peace and blessings be upon him) when a Bedouin came to him (peace and blessings be upon him) with a rabbit?" A man from the gathering said: "I was present. The Bedouin had brought it cleaned and prepared, to present it as a gift to the Messenger of Allah (peace and blessings be upon him). The Messenger of Allah (peace and blessings be upon him) said: 'All of you, eat.' At this a man among those present said: O Messenger of Allah! I saw it bleeding. So the people ate it, but the Bedouin did not eat. The Prophet (peace and blessings be upon him) asked him: 'Why do you not eat?' He said: I am fasting. He (peace and blessings be upon him) said: 'Then why did you not fast the White Days (Ayyam al-Bid: the 13th, 14th and 15th of the lunar month)?'"
