What is the ruling on a mother giving gifts to her male children but not her female children from her private wealth?

The Sharia commands justice between children in gifts and endowments, and this is obligatory, giving the male the same as the female. The mother is like the father in this obligation. It is permissible to favor some children due to their need, and not merely for the sake of preference. If the mother favors some of her children without a valid reason, she must equalize by returning what she favored them with, or by completing the share of the others. This applies if the gift is from the mother's private wealth. The ruling differs if the money is the husband's retirement pension.
