Yajuj and Majuj were two two disbelieving tribes of Turks, descended from Yafith (Japheth), the father of Turks, one of the son of Noah. According to the descriptions they have small eyes, small, flat noses and wide faces. Their faces look like hammered-out shields.They were t0o powerful but barbarous tribes causing prejudice and chaos on the Earth , killed God-fearing men and devastated all their provisions and plantation.
At the time of Ibrahim(pbuh) there was a king called Dhul Qarnayn. He performed Tawaf around the Kabah with Ibrahim(pbuh), when he first built it; Dhul Qarnayn believed and followed him. Dhul Qarnayn was a good man and a great king. Allah gave him great power and he ruled the east and the west.
He was travelling towards east, he reached a pass between two mountains, through which people were coming out.They did not understand anything, because they were so isolated.
Yajuj and Majuj were spreading mischief on earth and were harming people. So the people sought help from Dhul Qarnayn.
They said: ‘O Dhul-Qarnayn! Verily! Yajuj and Majuj are doing great mischief in the land. Shall we then pay you a tribute in order that you might erect a barrier between us and them?’
He said: ‘That (wealth, authority and power) in which my Lord has established me is better (than your tribute). So help me with strength (of men), I will erect between you and them a barrier.’
So Dhul Qarnayn built a wall by mixing iron, copper and tar. Thus, Dhul Qarnayn restrained Yajuj and Majuj behind the wall.
They tried to penetrate the wall or to climb it but they could not succeed as the wall was so huge and smooth. They began to dig and they have been digging for centuries. They will dig the wall every night trying to escape, only to find each morning that the wall has been restored by Allah. They will continue to do so until the time when Allah decrees that they come out.
At that time the wall will collapse, and Yajuj & Majuj will rush out in all directions in large numbers,spreading violence, uprooting plants, killing people.
They will spread mischief on earth and no one will be able to resist them. Their appearance will be one of the signs of the end times.
Yajuj and Majuj will shoot at the sky, hoping to destroy heaven. When Esa(pbuh) prays against them, Allah will send a kind of worm in the napes of their necks that will fill their ears and noses and they will be killed.
