Hazrat Aisha (may Allah be pleased with her) narrated that in Madinah we used to preserve the meat of sacrifice by applying salt to it, and then we would present it to the Messenger of Allah (peace and blessings be upon him). Then the Messenger of Allah (peace and blessings be upon him) said: "Do not eat the meat of sacrifice for more than three days." This command was not obligatory, rather the intention of the Prophet (peace and blessings be upon him) was that we should feed the meat of sacrifice (to those people as well who had not performed sacrifice), and Allah knows best.
