Is it permissible to slaughter a male goat for the 'Aqiqah?

The majority of scholars hold that the sheep sufficient for 'Aqiqah is the same as that sufficient for Udhiyah (sacrifice), and it is stipulated that it must be a "Thaniyyah," meaning it has shed its two front teeth and new ones have grown in their place. This is based on the Prophet's (peace be upon him) saying: "Do not slaughter except a Musinnah, unless it is difficult for you, in which case you may slaughter a Jadha'ah of sheep."

A "Musinnah" is a Thaniyyah among camels, cattle, and sheep. Accordingly, slaughtering a kid (jady) is not sufficient for 'Aqiqah unless it refers to a goat that has passed one year of age.
