I have a son who is 40 years old

Q 2: Is it permissible for a man who cannot speak to marry a normal girl who can speak? Is it permissible to have a conversation with her in the street, given that she is wearing Niqab (face veil)?

A: If the mentioned girl agrees to marry him after knowing his condition, it is permissible for him to marry her. (Part No. 18; Page No. 193) May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
