Musannaf Ibn Abi Shayba 37:608

Abu Usama narrated to us, he said: Abdullah bin al-Walid narrated to us, he said: I heard Muhammad bin Abd al-Rahman bin Abi Dhi'b saying: Abu Hurayrah said: "By Allah, if you knew what I know, you would laugh little and weep much. And if you knew what I know, you would laugh little and weep much. By Allah, killing and death will surely befall this tribe of Quraysh until the traveler comes to the 'Kuna'—Abu Usama said: meaning the 'Kunasa' (rubbish heap)—and finds there the sandal of a Qurayshi."
