Sayyiduna Abdullah bin Umar (may Allah be pleased with him) says: We were sitting with the Messenger of Allah (peace and blessings be upon him) discussing tribulations. He also mentioned many tribulations, including the tribulation of Ahlaas. A man asked: O Messenger of Allah! What is meant by the tribulation of Ahlaas? The Prophet (peace and blessings be upon him) said: The tribulation of Ahlaas refers to a time of war, conflict, and destruction. Then the tribulation of prosperity and ease will emerge; its beginning, end, leadership, and responsibility will be in the hands of a man who, according to his own assumption, will be from me, but he will not be from me. My friends are only the pious people. Then people will make peace with a person who will not be permanently fit or worthy of kingship. After that, a tribulation consisting of dreadful calamity and disaster will appear; it will shake every individual of this Ummah. When it will be said that the tribulation has ended, it will intensify and come forth even more. A person will be a believer in the morning and a disbeliever by evening. People will split into two groups: one group will be of believers, in which there will be no hypocrisy, and the other group will be of hypocrites, in which there will be no faith. When the matter reaches this point, then await the Dajjal; he may come that very day, or he may come the next day.
