Does divorce take effect and is expiation obligatory for someone who denied his marriage with the intention of arousing the curiosity of the caller, and not with the intention of divorce?

The summary of the answer is that the jurists have stipulated that if someone is asked, "Do you have a wife?" and he replies, "No," then divorce does not occur by that, unless he intended to initiate divorce with his utterance, in which case it does occur. Some of them said that it does not occur at all, whether he intended divorce or not, but this opinion is less preferred. If there is no need for lying, then one should not resort to it.
