The advent of the creature is before this world is ended, and the new world is brought into being:ِ

      ``And when the word of punishment came to pass against them, We will bring out of the earth a creature for them, who speaks to them, telling that the people had not faith in our signs. Qurän does not give enough detail, as to who or how the creature is. From the verse we can understand that he is a moving creature, which may mean he is very hardy and active. He is also intelligent and well aware of the social conditions, that he makes speech, and informs the people that their difficulties are due to their lack of faith in the signs of God.

      Of course, the creature, through some Islamic, traditions, has been illustrated well enough. It is narrated that the creature is one of the signs and evidences that the Resurrection Day would occur soon after.

      Some of the expounders of Qurän, have understood the moving creature to be some sort of a superman who is very active, and through his earnest movements will separate the line of the believers from the non-believers and in particular, that of the hypocrites.

      There are some traditions that he is Hazrat Imam Ali (AS) and some other commentators like, ``ABULFOTUH RAZI'' have understood the creature to be Hazrat Al-Mahdi (AS), who is the 12th and the last Imam of the Shiite sect of Islam.

      Whoever, or whatever, the moving creature of the earth might be, he will admonish people that they arrogantly and without having knowledge have rejected the signs of God, and provided for their ruin, with their own hands. Then God's decree against the non-believers will be executed, while they have nothing to say for being sure that they are guilty.

REJ-AT = RETURN

      Some scholars have taken moving creature of the earth, to be one of the signs of ``REJ-AT''.

      The Arabic, ``Rej-at'' which means, ``THE RETURN'' is a sure incident which will happen, according to the Shiite Doctrine. This will happen after the advent of Al-Mahdi, and before the Resurrection Day. Thereby a group of believers and a troop of non-believers will return back to life. The believers will then develop to higher ranks in their way of evolution, and the non-believers will be punished severely for their oppressions.

      This Return is not general, and for all. It rather is applicable to certain people, specified from both parties.

      Jurisprudents say that, the Return is not one of the necessary principles of Shiite; and those who have denied it, have not been excommunicated from the sect.
