Allah's Messenger (ﷺ) said, "The Hour will not be established till: (1) two big groups fight each other whereupon there will be a great number of casualties on both sides and they will be following one and the same religious doctrine, (2) about thirty Dajjâls (liars) appear, and each one of them will claim that he is Allâh's Messenger (ﷺ), (3) the religious knowledge is taken away (by the death of religious scholars) (4) earthquakes will increase in number (5) time will pass quickly, (6) Al-Fitan (trials and afflictions etc.) will appear, (7) Al-Harj, (i.e., killing) will increase, (8) wealth will be in abundance SO abundant that a wealthy person will worry lest nobody should accept his Sadaqa, and whenever he will present it to someone, that person (to whom it will be offered) will say, 'I am not in need of it, (9) the people compete with one another in constructing high buildings, (10) a man when passing by a grave of someone will say, 'Would that I were in his place (11) and till the sun rises from the west. So when the sun will rise and the people will see it (rising from the west) they will all believe (embrace Islâm) but that will be the time when: (As Allâh said,) " No good will it do to a person to believe then, if he (or she) believed not before, nor earned good (by performing deeds of righteousness) through his (or her) Faith." (V.6:158). And the Hour will be established while two men spreading a garment in front of them but they will not be able to sell it, nor fold it up; and the Hour will be established when a man has milked his she-camel and has taken away the milk but he will not be able to drink it; and the Hour will be established before a man repairing a tank (for his livestock) is able to water (his animals) in it; and the Hour will be established when a person has raised a morsel (of food) to his mouth but will not be able to eat it."
