What is the recommended practice (sunnah) to be performed on the seventh day for a newborn?

Our brother has a final question. He says: When a boy or girl is born, we call the adhan in his right ear and the iqamah in his left. On the seventh day, we hold a walimah (wedding feast) where we buy some meat and chicken and invite friends to it. What is your opinion on this? Please guide us. May Allah reward you with good.
Answer: The sunnah in this matter is that the believer slaughters a sacrificial animal from sheep for a female, and two sacrificial animals for a male, of the same type as the udhiyah (sacrifice), either a two-year-old goat or a one-year-old sheep. This is called the 'aqiqah, and it is also called al-nasiqah. Some people call it al-tamimah. It is a sunnah commanded by the Prophet (peace and blessings be upon him): two for a male and one for a female. Chicken or meat bought from the market does not suffice. Rather, a sacrificial animal must be slaughtered, either a one-year-old sheep or a two-year-old goat. One is slaughtered for a female, and two sheep are slaughtered for a male. This is the sunnah. He cooks them in his house and invites to them whomever he wishes from his relatives, neighbors, and friends, and distributes some of it to whomever he wishes. This is the sunnah. And if he distributes all of it, there is no harm. Yes.
