Sunan an-Nasa'i, Book 41, Hadith 9 (In-Book) ⓘ

It was narrated from Nubaishah, a man of Hudhail, that the Prophet said: "I used to forbid you to store the meat of the sacrifices for more than three days so that there would be enough for everyone. But now Allah, the mighty and sublime, has bestowed plenty upon us, so eat some, give some in charity and store some, For these days are the days of eating, drinking and remembering Allah." A man said: "O Messenger of Allah, we used to sacrifice the 'Atirah during the Jahiliyyah in Rajab; what do you command us to do?" He said: "Sacrifice to Allah, the Mighty and Sublime, whatever month it is, do good for the sake of Allah, the Mighty and Sublime, and feed (the poor)." He said: "O Messenger of Allah, we used to sacrifice the Fara' during the Jahiliyyah; what do you command us to do?" He said: "For every flock of grazing animals, feed the firstborn as you feed the rest of your flock, until it reaches an age where it could be used to carry loads, then sacrifice it, and give its meat in charity to the wayfarer, for that is good."
