Should a man be told of his wife’s immoral conduct?

 

Someone found out that another man’s wife is committing zinaa. Does he have to tell her husband?

Praise be to Allaah. 

We put this question
to Shaykh ‘Abd-Allaah ibn Jibreen, may Allaah preserve him, who answered
as follows:

If she persists and
is admonished but does not repent, then in this case we think that it
is obligatory to tell her husband lest “his bed be corrupted” (i.e.,
lest his honour is compromised and/or a child be born that is not his
and thus the lineage is corrupted). And Allaah knows best.
