Question: how will yajuj and majuj die?
Answer: Yajuj and Majuj are the Arabic names for Gog and Magog. Dhu l-Qarnayn directs them to bring pieces of iron, which are melted in a fire to form a wall that can neither be scaled nor pierced, barring the way between two cliffs. ... When they fire their arrows against God, he will kill them all in one night.
