Is it permissible for a woman to grant a gift to her daughter, favoring her over her two sons, because her two sons consumed her right and her sister's right from the father's inheritance?

The preponderant opinion is that it is obligatory to equalize among children in giving, and it is not permissible to favor some of them unless there is a legitimate reason. The transgression of the two sons — by taking the share of the mother and sister from the inheritance, wronging them, cutting off ties of kinship, and disobeying their mother — justifies the mother favoring the daughter and disinheriting these two sons. The mother and sister have the right to sue them to reclaim their share.
