With a glance at the history of revealed Prophets, religious teachings and the speeches of religious leaders like Imam Ali, one would directly perceive that Prophets` mission includes earthly life and the hereafter both. Now the question occurs as: why has the domain of Prophets` mission limited and the greatest part of its teachings suppressed and its vital application left? It is hypothesized that complete program of Islamic leadership including prophecy, Imamate and faqih guardianship has refuted secularism, though some defending it try to attribute low importance to religion and its part in human life. As explained in the paper, in Alawi School, however, the theory is refuted; its principles are known as descriptive and, therefore, exposed to fault and may not answer human necessary needs. Such being the case, human essential need to religion and revealed teachings is not temporary. For human needs may not be satisfied by human limit knowledge and it is only Islam that supported by absolute knowledge can satisfied them.
