Must a drug-addicted son be given his monetary share from the rent of agricultural land, and is it permissible to sell his share of the land, knowing that he squanders money?

The matter must be referred to the judiciary to obtain a ruling interdicting the elder son due to his imprudence, as the majority of jurists stipulate a ruling from the ruler for imposing an interdiction on an imprudent person. As for the mother directly interdicting him herself, it is permissible according to the view that validates the mother's guardianship over wealth, which is a point of contention among scholars. Regarding restricting the right to purchase a person's share of land to his family, there is no basis for it, unless they are partners in the land, in which case they have the right of pre-emption.
