It is narrated from Sayyiduna Nabeesha (may Allah be pleased with him) that the Noble Prophet (peace and blessings be upon him) said: "We had forbidden you from eating the meat of sacrifice after three days so that it would suffice for you, but now there is abundance, so eat, store, and earn reward." Imam Darimi (may Allah have mercy on him) said: The meaning of «اتجروا» is to earn reward, that is, by giving charity and alms.
