Is the 'Aqiqah obligatory for the poor and the rich?

This questioner (Sa'd . N. A. al-Dosari) from Riyadh says: Is the 'Aqiqah obligatory for the poor and the rich? And is it obligatory for the father of the newborn to pay the value of this 'Aqiqah, or does the grandfather buy it, or what? May Allah reward you with good.
Answer: The 'Aqiqah is the 'Aqiqah, and it is the sacrifice. Some of the common people call it the 'Aqiqah. It is a recommended practice (sunnah) for the man and for the woman. For a male child, it is two, meaning two heads of sheep, whether they are sheep or goats, male or female. For a female child, it is one. This is the recommended practice (sunnah) to be slaughtered on the seventh day: two for a male on the seventh day, and one for a female. This is what is best. The father slaughters it; it is a recommended practice (sunnah) for the father, not obligatory. It is not obligatory, but it is a recommended practice (sunnah) for the father. The grandfather takes his place if he is not present. And if the mother slaughters it, that is sufficient. Yes.
And if it is not slaughtered on the seventh day, it is slaughtered after that... on the fourteenth, on the twenty-first, or after that, there is no harm. Even if it is after a year or two years, if it becomes easy for them to do so. But it is recommended (mustahabb), not obligatory; it is a confirmed recommended practice (sunnah muakkadah).
