Are Gog and Magog alive and imprisoned behind the wall built by Dhul-Qarnayn, and is this wall real or imaginary?

Gog and Magog are two existing nations from the Children of Adam, and the barrier built by Dhul-Qarnayn is a physical barrier made of iron and copper. The evidence for their existence today is the Hadith of Abu Hurayrah, may Allah be pleased with him, that they dig every day, and the Hadith of Zaynab bint Jahsh, may Allah be pleased with her, that the Prophet, peace and blessings be upon him, entered in a state of fear saying: "Woe to the Arabs from an evil that has drawn near! Today, a hole has been opened in the barrier of Gog and Magog like this," and he made a circle with his thumb and forefinger.
