Re: Hitting wife
If he is that religious, then he should know that there are several steps he needs to take. Anyway, an imam or someone with a lot of religious knowledge whom he'd respect may be the best person to intervene in such a situation, where he is explained how he is misinterpreting his religion and then given proper guidance as to what to do.
Bottom line is that an intervention is needed because either the entire town will be talking about him eventually, or the situation has the potential to deteriorate.
