In The Road to Paradise Maulana Wahiduddin Khan explains that the world of nature functions at the zero defect level. Everything here is a final model. Man has been created in his final shape. Yet we find human life in this world imperfect to an extreme degree. It is marred by all kinds of evil. This dualism in one and the same universe demands as a logical necessity that this contradiction be brought to an end. Man should also attain to a perfect life as does the rest of the world. Yet this difference is not an evil. In fact, it is in accord with God’s creation plan. God, according to His plan of creation has made a totally perfect world called paradise. But the entry to this world is not open to all, being on a selective basis. It is only those who, in their life before death, come up to the standard of the citizenship of paradise, who will be granted an abode in this perfect world of paradise.
