Musnad Ahmad 1164:3

'Abd al-Rahman ibn Mahdi narrated to us, from Sufyan, from Salamah—meaning Ibn Kuhayl—from Abu Idris, from Ibn Safwan, from Safiyyah bint Huyayy, from the Prophet (peace and blessings of Allah be upon him), who said: "People will not cease to raid this House until, when they are in a desert of the earth, the first of them and the last of them will be swallowed up, and the middle of them will not be saved." They said: "O Messenger of Allah, will there be among them those who are coerced?" He said: "Allah will resurrect them according to what is in their souls."
