What is the religious ruling concerning the house and the plot of land upon which it was built, given that the husband built it on the land of his deceased wife, which she inherited from her father, and that their infant daughter is currently living with her maternal grandmother?

If a man builds a house for his wife on her land, which her father gifted to her with the intention of ownership, then the house and the land become her property through possession and acceptance. This gift cannot be revoked. Therefore, the house and the land are considered an inheritance from the deceased woman and are distributed along with her other possessions among the heirs according to their prescribed shares, noting that most of the deceased wife's wealth will return to her husband and daughter if she has no other child.
