It is narrated from Sayyiduna Ibn Umar (may Allah be pleased with them both) that the Noble Prophet (peace and blessings be upon him) said: "No person should eat from the meat of his sacrificial animal for more than three days." For this reason, Sayyiduna Umar (may Allah be pleased with him) would not eat the meat of the sacrificial animal after sunset on the third day (later this ruling was abrogated).
