The Ruling on Justice Between Siblings

One of the female listeners, who has a tattoo, sent a message saying: She has twin siblings, a sister and a brother, and she asks: Is it obligatory to be just in dealing with them and in giving them everything?
Answer: It is not obligatory; this applies only to children. The Prophet (peace and blessings be upon him) said: As for brothers, maternal aunts, paternal aunts, and other relatives, it is not obligatory to be just among them. However, a believer should be wise; if a lack of justice among them may cause problems and enmity, the giver should be just and seek fairness so that no problems arise between him and his relatives. If it is your brother and your sister, and you give to the brother and leave the sister, there may be problems between you and her, so be good to her , give to her and to him, and be present for both of them. Likewise, if you give to her and leave him, there may be problems, so be good to both of them. But if nothing results from it and no harm occurs, there is no harm in giving her what she needs, or giving him what he needs, or giving him something special or giving her something special; there is nothing wrong with this. Yes.
The presenter: May Allah reward you. Perhaps our sister is referring to the issue of justice between twins specifically?
The Shaykh: No, it is not required, neither for twins nor for others. This applies only to children. She may not favor some children over others, whether male or female, due to the saying of the Prophet (peace and blessings be upon him): . Yes.
