The Hour will not come until the sun rises from the west, and when it rises and people see it, they will all believe

The Prophet (may Allah's peace and blessings be upon him) reports that among the major portents of the Hour is that the sun will rise from the west instead of the east, and when people see it, they will all believe. At that point, the belief of a disbeliever will not benefit him, nor will the righteous deeds or repentance be of any avail.

Then, the Prophet (may Allah's peace and blessings be upon him) mentioned that the Hour will come so abruptly that people will be busy with their life affairs. So, the Hour will come when a buyer and a seller have spread out a garment between them, but they cannot finish their transaction or fold up the garment. And the Hour will come when a man has taken milk from his she-camel but will not be able to drink it.

And the Hour will come when a man is repairing his tank, but he will not be able to water his livestock therefrom. And the Hour will come when a man has lifted a morsel to his mouth but will not be able to eat it.
