سنن ابن ماجه

It was narrated from Safiyyah that the Messenger of Allah (ﷺ) said: “People will not stop attacking this House until an army attacks, until when they are in Baida’, the first and the last of them will be swallowed by the earth, and the middle of them will not be saved.’” I said: “What if there are those among them who were forced (to join the army)?” He said: “Allah will resurrect them according to what is in the hearts.”
