"And there is a ban on (the people of) a TOWN which we destroyed: that they (the people of the town) shall not return (to reclaim their town) until Gog and Magog are released and (eventually) they descend from every height (or spread out in every direction)." (Al-Anbiyah 21:95-6)
So according to him the "Town" is Jerusalem...If this really is the case, then it means they have already been released right?
