I heard Allah's Messenger (ﷺ) as saying: The (system) of night and day would not end until the people have taken to the worship of Lat and 'Uzza. I said: Allah's Messenger, I think when Allah has revealed this verse:" He it is Who has sent His Messenger with right guidance, and true religion, so that He may cause it to prevail upon all religions, though the polytheists are averse (to it)" (ix. 33), it implies that (this promise) is going to be fulfilled. Thereupon he (Allah's Apostle) said: It would happen as Allah would like. Then Allah would send the sweet fragrant air by which everyone who has even a mustard grain of faith in Him would die and those only would survive who would have no goodness in them. And they would revert to the religion of their forefathers.
By Him in Whose Hand is my life, a time would come when the murderer would not know why he has committed the murder, and the victim would not know why he has been killed.
The world would not come to an end until a day would come to the people on which the murderer would not know as to why he has killed and the slain would not know as to why he has been murdered. It would be said: Why would It happen? To which he replied: It would be because of general massacre and bloodshed. And the slaughterers and the slain would be in Fire, and in the narration of Ibn Aban, the name of Abu Isma'il has been mentioned.
The Last Hour would not come unless you fight with people whose faces are like hammered shields and the Last Hour would not come until you would fight against those wearing the shoes of hair.
