According to the fatwa, if a person builds a new house and happily invites friends and relatives for a meal, then this is permissible in Shariah. Islamic scholars explain that such meals are allowed when they are done to celebrate a new blessing.
Classical books mention that food prepared for any new joy—such as marriage, returning from travel, or building a house—is considered good and recommended. Therefore, arranging a simple meal after building a new house is allowed and carries no issue in Islamic ruling, as long as it is done without showing off or burden.
This fatwa clearly shows that inviting people for a house opening feast is permitted in Islam.
