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.
