Is it necessary to repeat the aqiqah, amend the birth and death certificates, and inform people about the error in determining the gender of the deceased newborn who was named Muhammad, given that after his burial and the performance of the aqiqah, it became clear that the baby was female, and was named "Nour Muhammad" between the spouses?

The aqiqah (sacrifice upon childbirth) is recommended for a newborn who dies before the seventh day, according to some scholars like the Shafi'is and Hanbalis. If the intention for the sacrifice was made for a specific newborn, the aqiqah is sufficient, even if you thought it was a male but it turned out to be female, because jurists have mentioned sufficiency in similar cases. It is also recommended to name the newborn with a female name if that is confirmed. There is no obligation to inform people of what happened, and the aqiqah is recommended, not obligatory, according to the majority of scholars.
