It is narrated from Hazrat Abu Huraira (may Allah be pleased with him) that the Noble Prophet (peace and blessings be upon him) said: The Hour will not be established until time draws near, so that a year will be like a month, a month like a week, a week like a day, a day like an hour, and an hour will be like the flare of a firebrand.
