سنن ابودوٗد · Hadith 4242

Narrated Abdullah ibn Umar: When we were sitting with the Messenger of Allah ﷺ, he talked about periods of trial (fitnahs), mentioning many of them. When he mentioned the one when people should stay in their houses, some asked him: Messenger of Allah, what is the trial (fitnah) of staying at home? He replied: It will be flight and plunder. Then will come a test which is pleasant. Its murkiness is due to the fact that it is produced by a man from the people of my house, who will assert that he belongs to me, whereas he does not, for my friends are only the God-fearing. Then the people will unite under a man who will be like a hip-bone on a rib. Then there will be the little black trial which will leave none of this community without giving him a slap, and when people say that it is finished, it will be extended. During it a man will be a believer in the morning and an infidel in the evening, so that the people will be in two camps: the camp of faith which will contain no hypocrisy, and the camp of hypocrisy which will contain no faith. When that happens, expect the Antichrist (Dajjal) that day or the next.
