Fath al-Rabbani

It is narrated from Sayyiduna Abu Hurairah (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: Yajuj and Majuj dig at the wall every day. When the sun is about to set, their leader says: Go back, you will dig it tomorrow. But when they come the next day, the wall is even stronger than before. (This happens every day) until their appointed time is fulfilled and Allah wills that they come out to the people. They will dig in the same way, and when the sun is about to set, this time their leader will say: Go back, if Allah wills, you will dig the rest tomorrow. This time he will say insha’Allah. The next day, when they come, they will find it in the same condition as they left it, so they will dig through it and come out to the people. They will drink up all the waters, and people, out of fear of them, will lock themselves in their forts. (After taking control of the earth) Yajuj and Majuj will shoot arrows towards the sky, and the arrows will return blood-stained. Seeing this, they will say: We have prevailed over the people of the earth and the people of the sky as well. Then Allah will create a worm in their necks, because of which they will die. The Messenger of Allah (peace and blessings be upon him) said: By Him in Whose hand is my soul! The animals of the earth will become fat and healthy by eating their flesh and blood.
