Sayyiduna Abu Hurairah (may Allah be pleased with him) narrates this statement of the Noble Prophet (peace and blessings be upon him): "The Hour will not be established until knowledge is taken away, tribulations appear, falsehood becomes widespread, time contracts, (markets) come close together, and killing becomes abundant." It was asked: What is meant by killing? The Noble Prophet (peace and blessings be upon him) said: "Killing."
