Praise be to Allah. Who are Yajuj and Majuj? There is no doubt that Yajuj and Majuj are two huge nations of the sons of Adam. Anyone who reads the story of Dhu’l-Qarnayn and how he dealt with this nation in Surat al-Kahf will know for sure that they exist and that the barrier which was built is not metaphorical or imaginary, but is a physical barrier built of iron and melted copper. The basic principle is that we should take this Quranic text as it is, without resorting to any kind of misinterpretation or trying to twist the intended meaning.
