Equality when giving wives gifts

Q: A woman from Abu `Arish in Jazan district submits a Fatwa request to Your Eminence. Her concern is as follows: For a long time, she lived with her husband in a small house in which her in-laws are living too. Her husband promised that he will build a bigger house for her exclusively when Allah makes things easier. Leading an easy life, he kept his promise and built a separate and large house where she lived for a period of time during which she gave birth to four daughters. The husband married a second wife (Part No. 16; Page No. 186) in a different town where he built a separate house. This wife gave birth to a son and a daughter. The first wife who sent this request asked her husband to register the long-awaited house in her name. The husband is confused for fear of being sinful if he accepts this demand. Is he sinful if he registers this house in her name and registers the other house built in the other country in the second wife's name?

A: If the reality is as you have mentioned, it is permissible for the husband to register each house in the name of each wife for whom it is built. May Allah grant us success. May peace and blessings of Allah be upon our Prophet Muhammad, his family and Companions!
