And the Messenger of Allah, peace and blessings be upon him, said: "The Hour will not be established until wealth becomes abundant among you, so much so that it will overflow, to the extent that a wealthy person will worry about who will accept his zakat from him." He, peace and blessings be upon him, said: "And knowledge will be taken away, and the time (of the Hour) will draw near, and tribulations will appear, and harj will become widespread." The people asked: O Messenger of Allah! What is (harj)? He, peace and blessings be upon him, said: "Killing and bloodshed, killing and bloodshed."
