Well, your guess is as good as mine…
I’m thinking, some sort of baptism?
I found this:
“Aqiqah involves sacrificing a goat or lamb on behalf of the child. It is giving thanks to Allah for the gift of a child. The meat is distributed to the poor, or it can be used to arrange a feast to which the poor as well as relatives and friends are invited.”
This is probably a hoax but it is nicely done and not far from the truth. 🙂
