Is the 'aqiqah (sacrifice for a newborn) valid if someone else performed it on behalf of my child using their own money with my permission?

Question:
May Allah reward you, Honorable Shaykh. A woman asks: A woman gave the 'aqiqah for my child on my behalf because she is wealthy and I am not. Is this 'aqiqah valid? Or must I return the money to her as a debt in my liability? Is this valid as my 'aqiqah, or must I return the money to her as a debt in my liability?

Answer:
No, this is good. If someone performed the 'aqiqah for your child, even if you are wealthy, if someone performed it for your child with your permission and you approved of it, there is no harm. There is no harm in that, because this is one of the acts of worship in which representation is permitted. It is a financial act of worship in which representation is permitted. So if someone represented you, bore the cost, and you gave him permission, and he slaughtered the 'aqiqah in the manner prescribed by the Shari'ah, then it is valid. This is good.
