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.
Sahih Muslim Book 54, Hadith 69
← Previous Hadith By Him, in Whose hand is my life, the world would not come to an end until a person would pass by a grave, would roll over it and express the desire that he should be in the place of the occupant of that grave not because of religious reasons but because of this calamity.

Sahih Muslim Book 54, Hadith 68 Next Hadith → 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.
