Is it permissible for a young man to stop giving his parents money from his salary in order to get married with it, especially since his father owns properties and refuses to sell any of them to facilitate his son's marriage?

If you can combine earning money for marriage with spending on your parents or giving them money that pleases them, this is a good thing, for the satisfaction of parents is among the most excellent acts of obedience. However, if you cannot combine the two matters, then there is no blame upon you for not spending on them, because their financial support is waived from you due to their possession of properties that they can sell and spend from their proceeds on themselves.
