Shiavault - a Vault of Shia Islamic Books The Methods of Propagation and Missionary Work Necessity of Propagation "And nor is it for the faithful that they should go forth (to war) all together; why should not then a company from every party of them go forth that they may acquire (proper) unders-tanding in religion, and that they may warn their people when they return unto them, so that they may be cautious?" Holy Qur'an (Tawba 9: 122) "And that there should be among you a group who call (mankind) unto virtue and enjoin what is good and forbid wrong; and these are they who shall be successful." Holy Qur'an (Al-e-Imran 3: 103) Since the dawn of human history, Allah, the Glorious, has sent messengers and prophets (a.s.) as guiders and reformers for the salvation of mankind, solving their social problems, resolving their ideologi-cal conflicts and calling them to the unity of Allah and worshiping Him alone.
The Holy Qur'an has recorded this fact: "…and there is not a people but a warner has gone among them." Holy Qur'an (Fatir 35:24) This was necessary because, to know Allah, the Glorious, to worship Him and to reform mankind cannot be achieved except by way of the messengers and the divine call. And it is not possible to know the hereafter, which is related to this world, nor is it possible to know the path of bliss and deliverance in the next world, except by divine guidance and explanation.
The consequence of the relationship between knowing Allah and worshipping Him, on the one hand, and the coming of the divine guidance and explanation of the reward that man deserves in the next world, on the other, is the principle of divine justice. This is because entitlement to reward is connected with faith and deeds and, likewise, faith and deeds are related to knowing and depending on Allah.
As a result of these, the Qur'an established the principle of divine justice and makes clear that there is responsibility and no recompense, sending of messengers and making the message, unless fater revelation reaches mankind.
