Abu Huraira reported God's messenger as saying, "The last hour will not come before two parties which make the same profession fight together and a great slaughter results, before about thirty lying dajjals are sent forth each of them asserting that he is God's messenger, before knowledge is withheld, earthquakes are abundant, the time becomes short, dissensions appear, and there is much harj, which means slaughter, before wealth is abundant and overflowing among you, before one who possesses property is anxious to find someone who will accept his sadaqa, before he offers it and the one to whom it is offered says he has no need of it, before people try to outstrip one another in building, before a man passes another's grave and expresses the desire that he were in his place, and before the sun rises in its place of setting. Then when it rises and people see it, they will all believe, but that is a time when a soul will not be benefited by faith it did not have before, or acquire any good from its faith. The last hour will certainly come when two men have spread out their garment between them, but they will not complete the transaction or fold up the garment; the last hour will certainly come when a man has gone off with the milk of his milch camel, but he will not taste it; the last hour will certainly come when a man is repairing his tank, but he will not water his camels from it; and the last hour will certainly come when one has raised his food to his mouth, but he will not taste it." (Bukhari and Muslim.)
