Musnad Ahmad Hadith 6713

It is narrated from Ibn Amr (may Allah be pleased with him) that someone asked the Noble Prophet (ﷺ) about "Aqiqah." The Noble Prophet (ﷺ) said: "Allah Almighty does not like 'Uquq' (disobedience)." It is as if the Noble Prophet (ﷺ) did not like the verbal similarity. The noble Companions (may Allah be pleased with them) submitted, "O Messenger of Allah! We are asking you regarding our children." The Noble Prophet (ﷺ) said: "Whoever among you wishes to offer a sacrifice on behalf of his child, let him slaughter two equal goats for a boy and one goat for a girl." Then someone asked about the sacrifice of the firstborn camel. The Noble Prophet (ﷺ) said: "This is valid, but if you leave it until it matures and becomes two or three years old, then you give it to someone for the sake of Allah as a riding animal or give it to widows, that is better than slaughtering it, smearing its meat with its hair, overturning your pot, and making your she-camel mad." Then someone asked about "Atirah." The Noble Prophet (ﷺ) said: "Atirah is valid." Someone asked Amr bin Shu'aib about the meaning of Atirah, so he explained that people used to slaughter a goat in the month of Rajab, cook it, eat it themselves, and feed others as well.
