It is narrated from Sayyiduna Uwaymir bin Ashqar (may Allah be pleased with him) that he slaughtered his sacrificial animal and prepared a dish (of food) from (its meat), then brought it to the Prophet (peace and blessings be upon him). He (peace and blessings be upon him) asked: "What is this?" He said: "It is from (the meat of) my sacrifice." He (peace and blessings be upon him) asked: "When did you slaughter it?" He said: "Before praying (the Eid prayer)." So he (peace and blessings be upon him) ordered him to repeat the sacrifice.
