Musnad Abu Ya'la al-Mawsili 209:129

Abu Khaythama narrated to us, Abd al-Samad ibn Abd al-Warith narrated to us, my father narrated to us, Ali ibn Zayd narrated to us, from al-Hasan, from his mother, from Umm Salamah, who said: The Messenger of Allah (may Allah bless him and grant him peace) woke up from his sleep while he was saying "Inna lillahi wa inna ilayhi raji'un" (To Allah we belong and to Him we shall return). She said: I said, "O Messenger of Allah, what is the matter with you?" He said, "A group of my nation will be swallowed by the earth. They will be sent against a man, so he will come to Makkah, and Allah will protect him from them, and they will be swallowed by the earth. Their place of destruction is one, but their sources are various." She said: I said, "O Messenger of Allah, how can their place of destruction be one while their sources are various?" He said, "Because among them are those who are compelled, so he comes compelled."
