vorode ye farde jadido to khonevadatoon tabrik migam:
translation: congratulation on having a new family member
This can be said as a congratulation to a friend when a new member has joined their family and become a member of the family, e.g. the brother is married and they have a new "sister in law"
It can also be used when a baby is born ( less common in this situation, as we have other expressions for this case)
