Does a mother have the right to entrust God with her son who became angry because she disposed of his money without his knowledge or permission, and is the son considered to be in the wrong for that?

The preponderant view is that the mother does not have the right to dispose of her child's money without his permission. However, the child is not permitted to treat her badly or verbally abuse her if she does so. If the discussion with her is gentle and polite to explain the mistake, there is no blame, and she should not get angry; rather, he should be kind to her. But if the discussion is harsh or impolite, then he has erred and must repent, apologize, and seek her رضا (pleasure/satisfaction).
