Thirdly...

Thirdly, the Mujiza should never be surpassed by any other person's extraordinary feat In other words, Mujiza should always remain beyond the reach of the people of the time and should always remain unchallenged and undefeated. Fourthly, the Shariah and religion which that person claims to bring from God must be according to the views of the right thinking people of his time based on perfection and intelligence.

Fifthly, that claimant of Nubuwwat or Imamat must follow and adhere to the rules and regulations of that Shariah himself. Sixthly, the ethical, moral and social life of the person who claims to show the Mujiza must be beyond reproach, most perfect and most noble in the eyes of the right thinking people of his time. Seventhly, his behaviour in private should not differ from that in public; his private life should be as blameless as his public life.

Eightly, the challenge given in connection with that Mujiza should not be limited to a time. It must be open during all the period when the Nubuwwat or Imamat of the claimant is supposed to continue. What Types of Miracles Were Given?

As it was the purpose of the Mujiza to convince the people that such things could not occur without the authority of Almighty God, it was essential that Mujiza should supercede that every branch of knowledge or expertise which was the most advanced in the time of the prophet or Imam concerned. Otherwise, the people could not be convinced that the Mujiza was really of such high standard which was beyond human capacity.

For example, if in a primitive society in which people do not know how to make a wooden wheel, a man comes with a cycle and says, "It is my Mujiza that I ride on this cycle and go from one place to another," the people may easily be fooled. But if such a man comes in an industrialized society even with a space rocket, nobody will believe that it is beyond human power.

To make people appreciate the genuine highest standard of a Mujiza, Allah always gave such miracles to his prophets which concerned that very science or art which was the most advanced in his time. So that the experts of that art or science could easily test, judge and then believe that the claim of Mujiza was genuine and really it was not in the power of a man to conjure such things himself. In the days of Prophet Musa (a.s.), magic was the most advanced art of the time.
