Sahih al-Bukhari 6506

Narrated Abu Huraira:Allah's Messenger (ﷺ) said, "The Hour will not be established till the sun rises from the west, and when it rises (from the west) and the people see it, then all of them will believe (in Allah). But that will be the time when 'No good it will do to a soul to believe then. If it believed not before.."' (6.158) The Hour will be established (so suddenly) that two persons spreading a garment between them will not be able to finish their bargain, nor will they be able to fold it up. The Hour will be established while a man is carrying the milk of his she-camel, but cannot drink it; and the Hour will be established when someone is not able to prepare the tank to water his livestock from it; and the Hour will be established when some of you has raised his food to his mouth but cannot eat it
