Praise be to
Allaah.
He should not marry his daughter to him unless he has
explained his situation and said, “I have such and such a disease.”
Then if they agree to that, then that is fine, otherwise the marriage
should not proceed, because if he conceals the matter from them he may
have cheated them and deceived them, and the woman may pass the disease
to her husband, or the husband may pass it to his wife, and to their
children after that. But if she accepts you and agrees, and accepts
the will and decree of Allaah, then that is OK
