Dhul Qarnayn, appears in the Quran, Surah Al-Kahf, Ayahs 83–101 as one who travels to east and west and erects a wall between a certain people and Gog and Magog. He was also known as Eram, and he lived at the time when prophet Jeremiah awoke from a slumber of 100 years. Dhul Qarnayn took Jeremiah on his quest to find the fountain of life. And Jeremiah is the one who found the fountain of life and drank from it.
Dhul Qarnayn is from the prophets and messengers who have return in the present day.
