Al-Bara bin Azib (RA) reported: Allahs Messenger ﷺ addressed us on the day of Nahr and said: None should sacrifice the animal unless he has completed the (Id) prayer. A person said: I have a milch goat of less than one year, better than two fat goats. Thereupon he said: Sacrifice it, and no goat of less than a year of age will be accepted as sacrifice after you.
