It is narrated from Sayyiduna Abu Burdah (may Allah be pleased with him) that once he submitted in the court of the Messenger (peace and blessings be upon him): O Messenger of Allah! We have slaughtered our goat very early. The Prophet (peace and blessings be upon him) asked: Even before the Eid prayer? I replied in the affirmative, so he said: Then it is just a meat goat. I said: O Messenger of Allah! We have a six-month-old kid which, in our eyes, is better than a year-old animal. The Prophet (peace and blessings be upon him) said: It will suffice for you, but after you, it will not suffice for anyone else.
