Musannaf Ibn Abi Shaybah 40345 — Reports on the tribulation

It is narrated from Sayyiduna Abu Hurayrah (may Allah be pleased with him) that a man said: "O Messenger of Allah (peace and blessings be upon him), when will the Hour come?" He (peace and blessings be upon him) said: "The one being asked about it does not know more than the one asking, but I will describe its signs to you: when a slave woman gives birth to her master, that is one of the signs of the Hour; and when the barefoot and naked become the chiefs of the people, that is one of the signs of the Hour; and when the shepherds of goats vie with one another in buildings, that too is one of the signs of the Hour. The knowledge of the Hour is among five things which none but Allah knows: 'Indeed, with Allah is the knowledge of the Hour, and He sends down the rain, and He knows what is in the wombs; and no soul knows what it will earn tomorrow, and no soul knows where it will die. Indeed, Allah Almighty is All-Knowing, All-Aware.' [Luqman: 34]"
