Is it permissible to give the mother from the money allocated to her monthly without informing her that it is from the deceased's estate, knowing that she forbids herself this money despite her need, and the judge has ruled that she is the sole beneficiary?

If the money is ill-gotten (haram), it is not permissible to give her from it; rather, it must be spent in accordance with the Sharia (Islamic law) on permissible expenditures. However, if the money is lawful (halal) and she has not relinquished ownership of it, then it is permissible to give her from it, because her children and their wealth belong to her when there is a need, as the Prophet, peace and blessings be upon him, said: "Indeed, your children are a gift from Allah to you; He grants to whom He wills females and grants to whom He wills males. They and their wealth are yours if you need them." It is recommended that she spend from her own private wealth due to the general saying of the Prophet, peace and blessings be upon him: "And whoever seeks self-sufficiency, Allah will make him self-sufficient; and whoever seeks independence, Allah will make him independent," and "The upper hand is better than the lower hand."
