When a man divorces his wife, he should not reveal her secrets or describe her in ways she dislikes, as this would constitute backbiting. Al-Ghazali (may Allah have mercy on him) mentioned in Ihya' `Ulum Ad-Din (2/52) among the matters that a husband should observe in divorce: "He should not reveal her secrets, neither during divorce nor marriage." There is a severe warning about this in the authentic Hadith related by Muslim from Abu Sa`id who said: The Messenger of Allah (peace and blessings of Allah be upon him) said: "The most serious betrayal in Allah's sight on the Day of Resurrection is that of a man who is intimate with his wife and she is intimate with him, then he reveals her secrets.""
