The more science and technology advances, the greater is the need for the observance and practice of the teachings and instructions of divine prophets in human societies. This is because science and technology provide only machines and instruments and by no means prevent their misuse by human beings.
The terrible rise in murder, other felonies, corruption, suicide and so forth clearly points to this very fact. If morality, which is a significant part of the teachings of divine prophets, does not prevail and govern in human societies, surely not only will advanced science and technology fail to ensure human peace and prosperity, but they will add to our problems and miseries. For the exploiters and colonialists utilize advanced technology and sciences for their own satanic purposes. They murder or make homeless millions of human beings as they have always done and trample upon the rights of the weak and the defenseless.
As a matter of fact, the only factor that can halter man's restive soul and control his stormy instincts and passions and thus utilize science and technology for human prosperity and pacific life is true morality, which originates in faith in God.
The moral teachings and precepts of the divine prophets and their moral behavior are the best means of leading man to his ideal life. It goes without saying that both in personal and in social life the observance of moral principles is required of all. However, for those who must lead societies and guide the people, this requirement is much greater, because, first, the one who is the instructor of society must himself be a model of supreme moral behavior and excellent human characteristics, so he will be able to wipe moral decay out of people's hearts and minds. Obviously if he himself is lacking in morality, he will fail to lead the people onto the path of humanity and virtue.
Second, the responsibility of leading human societies is so great and crucial that no one can successfully perform it unless he has perfect morals. For this reason, God selected his prophets from among those who possessed exalted spirits, great tolerance, extraordinary patience, and other excellent moral characteristics. It was with this weapon of morality that divine prophets overturned the debased societies that were plunged in corruption and led the ignorant people who had gone astray onto the path of virtue and salvation.
In the Glorious Qur'an, Almighty God has addressed the Prophet Muhammad (pbuh): "Thus it is due to mercy from God that you deal with them gently, and had you been rough, hard-hearted, they would certainly have dispersed from around you." (3:159)
The sublime celestial morals of the Prophet Muhammad (pbuh) brought about the waves of the revolution of Islam first in Arabian society and afterwards all over the world. In the light of this all-embracing spiritual and intellectual resurrection, dispersion turned into unity, unchastity into chastity and virtue, idleness into hard work and industry, selfishness to altruism, and Arab arrogance to modesty and affection. Men and women were thus trained to become models of good moral behavior and have altruistic manners forever. The morals of the Holy Prophet Muhammad (pbuh) were so sublime and praiseworthy that Almighty God has regarded them as great. "And truly you (Muhammad) possess great morals." (68:4)
