An uncle of mine called Abu Burda offered his sacrifice before the prayer. The Messenger of Allah ﷺ said to him, "Your sacrifice is just a piece of meat for your family."He replied, "Messenger of Allah, I have a young domestic goat, a yearling."The Prophet said, "Slaughter it, but it will not be valid for anyone other than you." This is the hadith.In another narration, he said, "I have a young milk-fed goat."
ضحى خال لي يقال له أبو بردة قبل الصلاة فقال له رسول الله ﷺ: شأنك شأة لحم فقال: يا رسول الله إن عندي داجنا جذعة من المعز؟ قال: اذبحها ولن تصلح لغيرك الحديث. وفي رواية: إن عندي عناق لبن.
This was narrated by Bukhari in the Book of Sacrifices (5556) and Muslim in the Book of Sacrifices (4:1961), both by way of Khalid bin Abdullah, from Mutarrif, from Amir (that is, Shaybi), from Bara bin Azib, as mentioned above. The other narration in Muslim (5:1961) comes by way of Dawud (that is, Ibn Abu Hind), from Shaybi, with the same wording.Regarding his statement, "I have a dajin," the dajin is a sheep that people feed and keep in their homes. It may also apply to animals other than sheep, including any bird or other creature that is kept and tends to stay in the household.Regarding his statement, "a jadha," this is a description of a specific age for livestock. Among sheep, it refers to one that has completed a full year, though some say it is younger than that. Among goats, it refers to one that has entered its second year. Among cattle, it refers to one that has completed three years. Among camels, it refers to one that has entered its fifth year.Regarding his statement, "an anaq that nurses on milk," the anaq is a female goat kid once it has grown strong but has not yet completed a full year. Its plural forms are anuq and unuq. So his statement, "an anaq that nurses on milk," means a small one, close to the age of still being suckled.
