The ruling on severing family ties due to refusing to marry the uncle's daughter

Question:
The reality is that they have a problem in this message. They ask the Shaykh to resolve it or answer it, may Allah reward you. They say: My son is twenty-five years old, and his uncle wanted to marry him to his daughter. When we learned that she is mentally ill, we rejected the idea of marrying our son to this girl. The uncle became very angry and started speaking ill of us to force our son to marry his sick daughter, whose illness they fear. His wife was in control of the matter, and the fates willed it, they say, so we cut ties with him. He does not visit us, and we do not visit him. We fear Allah, so will we be sinful for not visiting him?

Answer:
First, the phrase "fate willed it" is not permissible. One should say "Allah the Exalted willed it," or "Allah intended it," or "Allah decreed it," attributing the matter to Allah the Exalted, not to fate.
Second, since the matter has ended and he did not marry his daughter to your son—whom you say has a mental illness or some condition you fear will affect the child or the offspring—praise be to Allah. This is up to the husband; a husband is not forced to marry someone he does not want, nor is a woman forced to marry someone she does not want. Rather, this is a matter of mutual choice between the two spouses. As for severing ties, you are sinning by doing so, as is he. You must repair the relationship between you, restore the ties, forget the past, and forgive one another. Yes.

May Allah reward you with good and bless you.
