Is the name "Ludun" (with a dammah on the Lām and Dāl) suitable for naming, and should it be changed for a one-year and seven-month-old girl, especially with concerns about the name's impact on the child's personality, and the husband's opposition to the change for reasons related to interpreting a previous dream and avoiding social confrontation and official procedures?

The interpretation of the dream is not necessarily correct, and one should not act upon it even if it were. Naming with this name is permissible as long as it does not involve a Sharia prohibition, such as worshipping other than Allah, or self-praise, or imitating the names of disbelievers. The spouses should strive for harmony, for discord is evil, and the matter is simple and should not be a cause for family dispute.
