Is a man's saying to his wife: "O بنت (bint - daughter/girl)," "O ابنتي (ibnati - my daughter)," "O أمي (ummi - my mother)," or "O راجل (rajul - man)" considered ẓihār? What are the phrases and conditions of ẓihār? And does what the tongue utters inside a closed mouth with a low voice count, and is it a condition for the mouth to be open for ẓihār to occur?

A man addressing his wife as "my daughter" or "my mother" is disliked (makrooh) but does not constitute Dhihar. The expressions of Dhihar include explicit forms, such as saying "You are to me like the back of my mother," which takes effect without intention. There are also allusive forms, such as saying "You are to me like my mother," which only takes effect with intention. For Dhihar to occur, the husband must be a mukallaf (accountable) and it must take place while the marital relationship exists. Dhihar is forbidden and is considered one of the major sins (kaba'ir). Divorce does not occur merely by intention; rather, it must be pronounced verbally by moving the tongue and lips.
