Sayyiduna Abu Sa'id Khudri (may Allah be pleased with him) narrates this statement of the Noble Prophet (peace and blessings be upon him): (Allah the Exalted says) "A day whose length will be fifty thousand years." It was asked how long this day will be. The Noble Prophet (peace and blessings be upon him) said: By the One in Whose hand is my soul, it will be easy (i.e., short) for the believer, to the extent that it will be even easier (i.e., shorter) for him than the time he used to take to perform an obligatory prayer in the world.
