What is the ruling of Islamic law regarding a mother who takes her son's money and belongings without his knowledge, knowing that he is not stingy with her nor does he rebuke her?

The Hadith, "You and your wealth belong to your father," indicates that the father is permitted to consume from and dispose of his son's wealth, as long as he is in need and not extravagant. The mother's ruling here is the same as the father's. The phrase "belong to your father" signifies permissibility, meaning the father may take from his son's wealth what does not harm him. Some scholars are of the view that the father takes from his son's wealth according to his need, and the son is obliged to earn and spend on his father if he is in need. The Hadith does not imply the permissibility of destroying wealth through extravagance and wastefulness.
