Sayyiduna Abu Hurairah (may Allah be pleased with him) narrates that the Prophet (peace and blessings of Allah be upon him) said: "The Hour will not be established until thirty Dajjals appear, each of them claiming that he is the Messenger of Allah, until wealth becomes widespread, trials will become apparent, and killing will be abundant." The people asked: "O Messenger of Allah (peace and blessings of Allah be upon him)! What is meant by 'harj'?" The Prophet (peace and blessings of Allah be upon him) replied: "Killing, killing."
