´It was narrated from Abu Musa that the Messenger of Allah (ﷺ) said:` “After you days will come when ignorance will become widespread, knowledge will disappear and there will be much Harj.” They said: “O Messenger of Allah, what is Harj?” He said: “Killing.”

´Abu Musa narrated that the Messenger of Allah (ﷺ) said:` “Before the Hour comes there will be Harj.” I said: “O Messenger of Allah, what is Harj?” He said: “Killing.” Some of the Muslims said: “O Messenger of Allah, now we kill such and such a number of idolaters in one year.” The Messenger of Allah (ﷺ) said: “That will not be like killing the idolaters, rather you will kill one another, until a man will kill his neighbor and son of the cousin and a relative.” Some of the people said: “O Messenger of Allah, will we be in our right minds that day?” The Messenger of Allah (ﷺ) said: “No, reason will be taken away from most of the people at that time, and there will be left the insignificant people who have no reason.”

Benefits and Issues: (1) Killing among Muslims over trivial matters is a sign of the Day of Judgment. This is such an evil trait which, until the recent past, did not exist in such abundance, even though many other tribulations were present.
(2) The purpose of forewarning about a tribulation is that every Muslim should strive harder to avoid it; therefore, it is the duty of the scholars and rulers to reflect upon its causes and strive for its prevention.
(3) A Muslim should act with understanding and should not make differences a justification for bloodshed.
(4) The differences among the noble Companions (radi Allahu anhum) were based on sincerity and due to misunderstanding. Therefore, it became possible for them to reform themselves, free from the influence of the propaganda of misguided people. Due to the selflessness and prudence of Hasan (radi Allahu anhu), the Muslims became united once again.
(5) When discussing the differences among the noble Companions (radi Allahu anhum), it is not permissible to adopt a tone that is contrary to respect regarding any Companion.
