Musannaf Ibn Abi Shayba 37:115

Affan narrated to us, he said: Imran al-Qattan narrated to us, from Qatadah, from Abu al-Khalil, from Abdullah ibn al-Harith, from Umm Salamah, who said: The Messenger of Allah (peace and blessings of Allah be upon him) said: "Allegiance will be pledged to a man between the Corner (al-Rukn) and the Station (al-Maqam), [in number] equal to the people of Badr. Then the groups (asa'ib) of Iraq and the substitutes (abdal) of Syria will come to him. Then an army from the people of Syria will raid them, until when they are at al-Bayda', they will be swallowed up by the earth. Then a man from Quraysh, whose maternal uncles are from Kalb, will raid them, and they will meet, and Allah will defeat them. It used to be said: The disappointed one is he who is disappointed of the spoils of Kalb."
