Prophets are men specially elected by God to be his messengers. Prophethood is indivisible, and the Qurʾān requires recognition of all prophets as such without discrimination. Yet they are not all equal, some of them being particularly outstanding in qualities of steadfastness and patience under trial. Abraham, Noah, Moses, and Jesus were such great prophets. As vindication of the truth of their mission, God often vests them with miracles: Abraham was saved from fire, Noah from the Deluge, and Moses from the pharaoh. Not only was Jesus born from the Virgin Mary, but God also saved him from crucifixion at the hands of the Jews. The conviction that God’s messengers are ultimately vindicated and saved is an integral part of the Qurʾānic doctrine.
All prophets are human and never part of divinity: they are the most perfect of humans who are recipients of revelation from God. When God wishes to speak to a human, he sends an angel messenger to him or makes him hear a voice or inspires him. Muhammad is accepted as the last prophet in this series and its greatest member, for in him all the messages of earlier prophets were consummated. The archangel Gabriel brought the Qurʾān down to the Prophet’s “heart.” Gabriel is represented by the Qurʾān as a spirit whom the Prophet could sometimes see and hear. According to early traditions, the Prophet’s revelations occurred in a state of trance when his normal consciousness was transformed. This state was accompanied by heavy sweating. The Qurʾān itself makes it clear that the revelations brought with them a sense of extraordinary weight: “If we were to send this Qurʾān down on a mountain, you would see it split asunder out of fear of God.”
This phenomenon at the same time was accompanied by an unshakable conviction that the message was from God, and the Qurʾān describes itself as the transcript of a heavenly “Mother Book” written on a “Preserved Tablet.” The conviction was of such an intensity that the Qurʾān categorically denies that it is from any earthly source, for in that case it would be liable to “manifold doubts and oscillations.” Eschatology (doctrine of last things)
In Islamic doctrine, on the Last Day, when the world will come to an end, the dead will be resurrected and a judgment will be pronounced on every person in accordance with his deeds. Although the Qurʾān in the main speaks of a personal judgment, there are several verses that speak of the resurrection of distinct communities that will be judged according to “their own book.” In conformity with this, the Qurʾān also speaks in several passages of the “death of communities,” each one of which has a definite term of life. The actual evaluation, however, will be for every individual, whatever the terms of reference of his performance. In order to prove that the resurrection will occur, the Qurʾān uses a moral and a physical argument. Because not all requital is meted out in this life, a final judgment is necessary to bring it to completion. Physically, God, who is all-powerful, has the ability to destroy and bring back to life all creatures, who are limited and are, therefore, subject to God’s limitless power.
Some Islamic schools deny the possibility of human intercession but most accept it, and in any case God himself, in his mercy, may forgive certain sinners. Those condemned will burn in hellfire, and those who are saved will enjoy the abiding joys of paradise. Hell and heaven are both spiritual and corporeal. Beside suffering in physical fire, the damned will also experience fire “in their hearts.” Similarly, the blessed will experience, besides corporeal enjoyment, the greatest happiness of divine pleasure. Social service
Because the purpose of human existence is submission to the Divine Will, as is the purpose of every other creature, God’s role in relation to human beings is that of the commander. Whereas the rest of nature obeys God automatically, humans are the only creatures that possess the choice to obey or disobey. With the deep-seated belief in Satan’s existence, humanity’s fundamental role becomes one of moral struggle, which constitutes the essence of human endeavour. Recognition of the unity of God does not simply rest in the intellect but entails consequences in terms of the moral struggle, which consists primarily in freeing oneself of narrowness of mind and smallness of heart. One must go out of oneself and expend one’s possessions for the sake of others.
The doctrine of social service, in terms of alleviating suffering and helping the needy, constitutes an integral part of Islamic teaching. Praying to God and other religious acts are deemed to be incomplete in the absence of active service to the needy. In regard to this matter, the Qurʾānic criticisms of human nature become very sharp: “Man is by nature timid; when evil befalls him, he panics, but when good things come to him he prevents them from reaching others.” It is Satan who whispers into a person’s ears that by spending for others he will become poor. God, on the contrary, promises prosperity in exchange for such expenditure, which constitutes a credit with God and grows much more than the money people invest in usury. Hoarding of wealth without recognizing the rights of the poor is threatened with the direst punishment in the hereafter and is declared to be one of the main causes of the decay of societies in this world. The practice of usury is forbidden.
With this socioeconomic doctrine cementing the bond of faith, there emerges the idea of a closely knit community of the faithful who are declared to be “brothers unto each other.” Muslims are described as “the middle community bearing witness on humankind,” “the best community produced for humankind,” whose function it is “to enjoin good and forbid evil” (Qurʾān). Cooperation and “good advice” within the community are emphasized, and a person who deliberately tries to harm the interests of the community is to be given exemplary punishment. Opponents from within the community are to be fought and reduced with armed force, if issues cannot be settled by persuasion and arbitration.
Because the mission of the community is to “enjoin good and forbid evil” so that “there is no mischief and corruption” on earth, the doctrine of jihad is the logical outcome. For the early community it was a basic religious concept. The lesser jihad, or holy striving, means an active struggle using armed force whenever necessary. The object of such striving is not the conversion of individuals to Islam but rather the gaining of political control over the collective affairs of societies to run them in accordance with the principles of Islam. Individual conversions occur as a by-product of this process when the power structure passes into the hands of the Muslim community. In fact, according to strict Muslim doctrine, conversions “by force” are forbidden, because after the revelation of the Qurʾān “good and evil have become distinct,” so that one may follow whichever one may prefer (Qurʾān), and it is also strictly prohibited to wage wars for the sake of acquiring worldly glory, power, and rule. With the establishment of the Muslim empire, however, the doctrine of the lesser jihad was modified by the leaders of the community. Their main concern had become the consolidation of the empire and its administration, and thus they interpreted the teaching in a defensive rather than in an expansive sense. The Khārijite sect, which held that “decision belongs to God alone,” insisted on continuous and relentless jihad, but its followers were virtually destroyed during the internecine wars in the 8th century.
