What Is Islam
Through a Biblical Lens?
Islam is one of the world’s major religions and teaches submission to the one God, called Allah in Arabic. Muslims regard Muhammad as the final prophet and the Qur’an as God’s revealed word. This page helps visitors understand what Islam teaches, what makes it distinct, and how its claims compare with the Bible.
A Clear Definition of Islam
Islam is a monotheistic religion that calls people to submit to the will of Allah. It teaches that Muhammad is the final messenger in a line of prophets that includes Adam, Abraham, Moses, and Jesus. The Qur’an is regarded in Islam as the final revelation, and the Muslim community looks to both the Qur’an and Hadith for doctrine and practice.
From a biblical lens, Islam should be understood on its own terms first. Then its teachings should be carefully compared with Scripture, especially on God’s nature, Jesus, sin, salvation, revelation, and the way a person is made right with God.
Many people know only fragments about Islam. Some know it through politics, some through culture, and others through comparison with Christianity. A serious exploration begins by asking: What does Islam actually teach?
Once that is understood, the next question is just as important: How do those teachings compare with the Bible’s teaching about God and salvation?
Educational Nuggets to Explore Islam
These core ideas help a visitor understand Islam clearly before comparing it to biblical Christianity.
Islam Means Submission
The very word Islam is tied to surrender or submission to the will of Allah. This idea is central to Muslim identity, devotion, law, and religious practice.
Allah Is One
Islam strongly emphasizes the absolute oneness of God. It rejects any division in God’s being and strongly rejects the Christian doctrine of the Trinity.
Muhammad Is the Final Prophet
Islam teaches that Muhammad is the last and greatest prophet in the line of divine messengers. His life and sayings shape Muslim belief and practice.
The Qur’an Is Central
Muslims believe the Qur’an is the final revelation from God, delivered to Muhammad. It functions as the supreme religious text in Islam.
Jesus Is Honored, But Not Divine
Islam speaks respectfully of Jesus as a prophet and Messiah, but denies that He is the Son of God, denies His deity, and does not accept the Christian understanding of His atoning death and resurrection.
Salvation Is Tied to Faith and Deeds
In Islam, judgment, obedience, repentance, and righteous deeds all matter. This differs sharply from the biblical teaching of salvation by grace through faith in Christ.
Key Islamic Beliefs to Understand
A serious comparison requires understanding the core pillars and teachings that shape Islamic life.
1. The Shahada
The Islamic declaration of faith is that there is no god but Allah and Muhammad is the messenger of Allah. This statement stands at the heart of Muslim identity and devotion.
2. Prayer, Fasting, and Almsgiving
Islamic life is structured by regular prayer, fasting during Ramadan, charitable giving, and devotion expressed in concrete religious practice.
3. Pilgrimage and Community
The Hajj to Mecca is a major pillar for those able to perform it. Islam also emphasizes belonging, ritual unity, and submission within the worldwide Muslim community.
4. Final Judgment
Islam teaches that all people will face judgment before Allah, and their belief, submission, and deeds matter in the final reckoning.
How Islam Differs from Biblical Christianity
These are some of the most important points of difference when viewed through a biblical lens.
The Nature of God
Islam rejects the Trinity. Christianity teaches one God in three persons: Father, Son, and Holy Spirit.
The Identity of Jesus
Islam teaches Jesus was a prophet, not God incarnate. Christianity teaches Jesus is the eternal Son made flesh and fully worthy of worship.
The Cross and Salvation
Biblical Christianity centers salvation on Christ’s atoning death and resurrection. Islam does not accept that same gospel foundation.
Authority and Revelation
Islam looks to the Qur’an as final revelation. Christianity looks to the Bible as God’s inspired Word and sees Christ as the climax of divine revelation.
