It is narrated from Sayyiduna Abu Musa Ash‘ari (may Allah be pleased with him) that the Messenger of Allah (peace and blessings of Allah be upon him) said:“Before the Day of Resurrection, there will be «هرج» .”Someone asked:“What is the meaning of «هرج» ?”He (peace and blessings of Allah be upon him) said:“It means killing. (Bear in mind that) it does not mean your killing of the polytheists, rather it means you will kill one another. (And the situation will reach such a point that) a man will kill his neighbor, his brother, his uncle, and his cousin.”The Companions asked:“Will we have our senses at that time?”He (peace and blessings of Allah be upon him) said:“The intellects of the people of that time will be taken away; they will be foolish. Most of them will think they are upon something (true), but they will not be upon anything (true).”Abu Musa said:“By the One in Whose hand is my soul! If we live to see such days, there will be only one way to escape from them: just as we entered, so we should leave from there, neither shedding anyone’s blood nor seizing anyone’s wealth.”
