Will the one who secretly gives charity to his poor aunt, using his father's money which he helped acquire, be rewarded, given the mother's dispute with the aunt?

The questioner is advised to try to reconcile between his aunt and his mother, because it is not permissible for a Muslim to abandon his brother for more than three nights. Giving charity to a poor aunt is considered charity and maintaining kinship ties. However, the money you give in charity must be your own, and it is not permissible to take it from someone else without their permission.
