Sahih Muslim | Book 22 | Hadith Number 4825

Narrated by Al-Bara' b. 'Azib
Al-Bara' b. 'Azib reported: Allah's Messenger (may peace be upon him) delivered an address on the day (of Nahr) in which he said: None of you should offer sacrifice of animals until he has completed the ('Id) prayer. Thereupon my maternal uncle said: Messenger of Allah, it is the day of meat, so it is not desirable (to keep my family in the state of longing). The rest of the hadith is the same.
