When a baby is born a marhaba event is usually held at his residence to welcome the baby's birth. Usually the marhaba program is held in conjunction with the aqiqoh event, which is to slaughter a goat.
1 goat slaughter for a baby girl then 2 for a baby boy. The marhaba program was filled with the reading of the albarjanzi maulid. And the marhaba program is not mandatory.
But marhaba events in Indonesian society are a common thing to do. Child birth is not complete without a marhaba program or reading of the birthday.
