The sister would be well advised to seek a counseller for both at the local Mosque. She may want to do her homework first to make sure the counsellor is not worse than her husband with his problem! Wonder how her husband is when it comes to dealing with those near and dear, the society at large and a citizen. Does he volunteer his time to worthy causes? Some may advise giving the marriage some time to see if things change otherwise seek a divorce. However not without trying first to see if the couple can come to some sort of compromise. Usually, fanatics are hard to change as deep down they think what they believe is 110% true and any flexibility shown would be satanic and sinful!! But one must not give up without trying.
