Will as long as they are married of course their nikah still is accepted it doesn't matter if they were separated for 2 years 10 or maybe 20 its OK as long as they are still married.

Just wanted to confirm. Yes it is, if it`s only a matter of being away for a long time. That doesn`t invalidate NikaaH. NikaaH is validated in the time of `aqd according to The Book of Allaah and the Sunnah of His Rasuul -sAaws... So how could time ever invalidate The Book and The Sunnah in this world, as they are not invalidated in eternity?
