Does informing the family about the reason for seeking divorce due to harm caused by the husband who cheats on his wife constitute a disclosure of his faults and a violation of his honor?

If you wish to separate from your husband due to his poor religious commitment and his negligence concerning forbidden acts, and you cannot do so without informing your family of his involvement in such acts, then there is no blame upon you for doing so. This is because such a situation permits backbiting to the extent of need, and concealing it is not obligatory. We note that expressing the husband's forbidden relations as "marital infidelity" might suggest that their condemnation stems solely from their being a betrayal of the wife, which is a concept contrary to Islamic law.
