Islamic Theology – Introduction
When it comes to Islamic Theology, the essential Muslim profession of faith is, “La ilaha illa Allah, Muhammadu Rasool Allah. [There is no God but God and Muhammad is the Messenger of God.]”
There are several sources for the study of Islam. Of foremost importance is the Qur’an itself. The Qur’an, (from the verb qara’a “to read” or “to recite”), is the holy book of Islam. Muslims believe that the Qur’an is the literal word of God (Arabic Allah) and the culmination of God’s revelation to mankind as revealed to Muhammad, the final prophet of humanity, over a period of twenty-three years through the angel Jibril. In this text we use primarily the translation of A. Yusuf Ali.1 While it is an older translation (sounding much like the King James Version of the Bible), it is well respected and widely known.
Ranking second to the Qur’an are the Hadith. The Hadith record the teachings, rulings, and actions of Muhammad as recounted by his early associates. Muslims believe that the Hadith are inspired by God, and thus are to be obeyed. Unlike the Qur’an, the Hadith enjoy a diversity of sources and divergence of readings. It is not uncommon to find a variety of forms of particular sayings or recollections of Muhammad’s actions. Different Muslim factions have different collections or highlight different actions or sayings recorded in the Hadith.
In addition to the Qur’an and the Hadith, we also turn to the works of noted scholars of Islam, whether Muslim or non-Muslim, as well as works popularly promoted by Islamic organizations. Throughout our presentation of Islam, we strive to be fair to the central features of the worldview, as well as to the diversity found among Muslims.
Islamic Theology – Central Beliefs
There are several central beliefs in Islamic Theology. First, Muslims believe in Unitarian theism. They reject the Christian doctrine of the Trinity and deny the deity of Jesus Christ. The one unforgivable sin is shirk, associating partners with God (i.e., polytheism). God is viewed as sovereign over humans and history, which has led to a discussion of the relationship between God’s sovereignty and human responsibility that parallels the same discussion among Christians.
Muslims also affirm the existence of angels and jinn, the latter being mischievous spirits made from fire. The angels exist in a hierarchy, with Gabriel at the top. Some believe that two angels attend each person, one recording good deeds and the other recording bad deeds.
The Qur’an teaches that God has sent prophets to every nation under heaven, though the final prophet is Muhammad. Also, while God gave special books to Moses, David, Jesus, and Muhammad, only the one given to Muhammad, the Qur’an, has been preserved without error, and is thus the ultimate authoritative scripture.
Capping off the central beliefs of Islam is the Day of Judgment, a day when every human being will face a weighing of deeds, both good and evil. Only if the weight of one’s good deeds surpasses that of one’s bad deeds can each person hope to enter into Paradise rather than descending into Hell.
Islamic Theology – Practice
Building upon the central beliefs of Islam (meaning “submission”), a devout Muslim (“one who submits”) is expected to practice the following five (or six) “pillars” of their religion:
Islamic Theology – Islam and Other Religions
Because Muhammad was the final prophet and the Qur’an God’s final revelation, Muslims reject all claims to new divine revelation or inspired prophets. Thus they are highly critical of groups branching off of pure Islamic Theology, such as the Baha’i,3 the Ahmadiyyah,4 and the Nation of Islam (i.e., “Black Muslims”),5 which assert prophetic continuation past Muhammad.
Even though there was a time when Muslims embraced adherents of other monotheistic faiths (such as Jews and Christians), this came to an end with the finished work of Muhammad and the full revelation of the Qur’an. Now only Muslims are accepted by God: “If anyone desires a religion other than Islam (submission to God), never will it be accepted of him; and in the Hereafter he will be in the ranks of those who have lost (all spiritual good)” (3:85).6
Islamic Theology – Conclusion
Rather than denying that the Old Testament is the Word of God, Christians affirm—in direct contrast to Muslim criticisms of the Bible—that it is God’s inspired Word and is useful for teaching, correction, rebuke, and instruction in godliness (1 Timothy 3:16–17). Islam is not to Christianity as Christianity is to the Old Testament. We can begin to illustrate the truthfulness of God’s Word to Muslims by showing the New Testament’s appeals to, dependence upon, and development from the Old Testament, as well as demonstrating our own high regard for the whole Bible—both Old and New Testaments.
