Is the money for the daughter, based on the fact that it was requested for her, or for both parents together? And if it is for the parents, how can the daughter repay the amount when she has used part of it and has no source of income? And if it is for the father only, how can she repay the money to him alone without causing discord between the parents?

The answer is summarized as follows: identifying the rightful recipient of a donation is based on the donor's intention. If the intention was solely to console the father, then the amount belongs to him alone, and the mother has no right to it. If the father donates the amount to his daughter, she is not obligated to return it unless the father retracts his donation and requests its retrieval. In that case, she is only required to return what remains of it, and she is not obligated to return what has been spent.
