Does a mother selling her apartment and dividing the new house into three apartments (for her, her son, and her other son), with the justification that the daughters have usufruct rights as long as they are alive, constitute an injustice to the daughters who have taken their share of the inheritance?

If a mother is to build a house for her sons and excludes her daughters from this gift, then this is considered an injustice in giving. Justice among children in gift-giving is obligatory according to some scholars, and the mother in this regard is like the father. Therefore, it is not permissible for the mother to favor sons over daughters unless there is a legitimate and recognized justification, such as the son's need or weakness, or his preoccupation with seeking knowledge, or if the other child is disobedient or uses what they receive to commit sin. It is advisable to consult scholars in the questioner's country for a precise clarification of the matter.
