The ruling on setting aside a sum of money for children in a bequest

Question:
I have a group of children. I helped some of them get married, and the rest have not yet married. Is it permissible for me to set aside a sum of money for their accounts, or not?

Answer:
No, this is not permissible. Marriage is part of financial maintenance. So, whoever among them has reached the age of marriage, you marry him off. And whoever has not reached it, you do not make a bequest for him, because he will not need to get married [immediately]. Marriage is part of maintenance, and maintenance varies; the maintenance of an adult is not the same as the maintenance of a child. So, you provide for each one only what he needs, and you do not make a bequest for him. The Prophet (peace and blessings be upon him) said: As for those who have reached the age of marriage while you are alive, you marry them off. And as for those who have not reached it, they will get married from their own wealth or from their own inheritance. Yes.
