2 verses have
barrier
in Edition Clear Qur'an by Talal Itani / Al-Kahf (The Cave)

18:52On the Day when He will say, “Call on My partners whom you have claimed.” They will call on them, but they will not answer them. And We will place between them a barrier.

18:93Until, when he reached the point separating the two barriers, he found beside them a people who could barely understand what is said.
