Musannaf Ibn Abi Shaybah 40310 — Reports on the tribulation

It is narrated from Sayyiduna Abu Hurayrah (may Allah be pleased with him) that he said: The Hour will not be established until the city of Heraclius, Caesar, is conquered, the callers to prayer call the adhan in it, and wealth is divided in it by the shield. They will return with a great deal of wealth, which the people will see. Then a crier will come to them saying that the Dajjal is behind you among your households. So they will throw away the wealth in their possession and turn to fighting him.
