How can the problem be solved regarding the father's division of his inheritance among his children, especially with one of the children refusing to take his share in cash and desiring to obtain a portion of the land, which raises the father's concerns about future problems occurring between the siblings?

The distribution of an inheritance is contingent upon the death of the inheritor. It is permissible for a father to bestow gifts upon his children during his lifetime, provided he is not afflicted with a life-threatening illness, and that possession of the gift is secured before the death of the donor or the onset of his life-threatening illness. Justice must be observed among them in the giving of gifts, necessitating the return of a gift if it involved undue favoritism. If the donor dies without returning it, it must be returned after his death, and the favored one must share equitably with his siblings. The children have the right to refuse the gift if justice is not achieved, while being careful to maintain proper respect towards their father.
