it has come down from traditions that when Mahdi emerges, he will rule as per his own knowledge; he will spread the true 'ma'aref' (divine sciences) amongst the people; he will remove the curtain obscuring the realities; he will enliven the holy religion of islam and will annul all that is not in islam and has been added to it such that people will imagine that Mahdi (a.s.) has brought a new religion and a new book.
verily, the execution of such reforms and dissemination of the realities the way it should and must be carried out requires much more perfect aptitudes and intellects than what we have today.
perhaps, postponement of Mahdi's emergence and continuation of his occultation is because of the hope of achieving perfection and development which, by the blessings of various sciences, is on the increase day by day.
the magazine 'al-helal' published an article about resurrection a few years ago under the title «does there exist a world after (the end of) this world?» and while replying to this question, it emphasised that a day will come when the literary and scientific world will reach its perfection like the material world.
surely, very soon men shall become aware of the literary, scientific and ethical world - more than today when he is cognisant of the material world. why shouldn't it be so especially when man has already perceived that the material world has ruined his rights and has put him in pressure and torment. soon man shall witness how the earth will be illuminated by the divine light and by means of Mahdi's emergence.
fourthly: test and examination for the people:
amongst Allah's ways which is still prevailing amongst his servants - right from the time he appointed the prophet - (and Allah's ways never alter or change) is the matter of human evaluation and examination so that the one who is destroyed is done so on the basis of witness, and proof and the one who is enlivened is done so on the basis of witness and proof and the level of their faith and reality is manifested - rather their own condition becomes known to themselves. verily, it often occurs that man's condition is unknown and remains a secret even for himself.
the divine shariats (laws) contains literary, material, wordly, spiritual, individual and social programs and teachings. this world is a school and the prophets are teachers and evangelists. every school or lesson requires an examination appropriate to it. the phenomenon, which occur in this world are a sort of examination. the effect of those lessons on the people can be ascertained predominantly be means of such examination. as Allah says:---
alif lam mim.
do men think that they will be left alone on saying, we believe, and not be tried?
