Dhul-Qarnayn's wall
A just king travels west and east, then builds an iron wall against Yajuj and Majuj. Scholars differ on who he was; some say Cyrus.
Dhul-Qarnayn
[Dhul-Qarnayn] said, "This is a mercy from my Lord; but when the promise of my Lord comes, He will make it level, and ever is the promise of my Lord true."
Quran 18:98
