It is narrated from Sayyiduna Nabeesha (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: "We had forbidden you from benefiting from the meat of sacrificial animals for more than three days, until Allah granted you financial ease. Now eat, store, and beware, these are the days of eating and drinking."
