Is it permissible for a woman to give her daughter a portion of her gold (1000 Jordanian Dinars) to help her buy a house, and will this result in a multiplied reward?

A mother is permitted to dispose of her owned gold, but she is not allowed to favor one of her daughters with a gift of gold unless there is a legitimate Sharia-compliant reason, such as the daughter's need. If the daughter is capable of earning, there is no justification for favoring her. Special allocation or preference is permissible if the other children give their permission and consent to it; otherwise, the mother commits a sin, and she must retract her gift or give to the others until they are equal.
