We were staying with the Messenger of Allah (ﷺ) at Arafat; he said: O people, every family must offer a sacrifice and an atirah. Do you know what the atirah is? It is what you call the Rajab sacrifice.

Abu Dawud said: 'Atirah has been abrogated, and this tradition is an abrogated one.

← Previous Hadith To proceed, the Messenger of Allah (ﷺ) said: Anyone who associates with a polytheist and lives with him is like him.

Sunan Abi Dawud Book 15, Hadith 311 Next Hadith → The Prophet (ﷺ) said: I have been commanded to celebrate festival ('Id) on the day of sacrifice, which Allah, Most High, has appointed for this community. A man said: If I do not find except a she-goat or a she-camel borrowed for milk or other benefits, should I sacrifice it? He said: No, but you should clip your hair , and nails, trim your moustaches, and shave your pubes. This is all your sacrifice in the eyes of Allah, Most High.
