Exit re entry Visa if Expire for Family members

Hi .

My family is going back on exit reentry visa from Saudi Arabia, and recently due to some health problem, they would not be able to return.

Now, I have already issued their exit re entry visa, and planned that once they exit, they don't re-enter, after that their Iqama will expire and everything will be ok.if they don't return what type of Problems will raise on my Iqama or Passport

Can anyone guide me what shall I do now, and what exactly are the rules ?

Probably nothing. But if they ever want to come back, it will be very difficult.
