Short Summary
Islam and Christianity share a long prophetic history and a common call to worship the One God. Muslims honor Isa (Jesus) (Peace Be Upon Him) as one of the greatest messengers of ALLAH and honor his mother Maryam (Mary) deeply. At the same time, Islam and Christianity differ fundamentally on the identity of Jesus, the Trinity, the crucifixion, salvation, and the question of final revelation. This article explains these shared themes and real differences with respect and evidence.

Introduction
Islam and Christianity are two of the most widely practiced religions in the world. They share prophetic figures, a strong emphasis on the One God, moral accountability, and concern for the Hereafter. They have also coexisted, exchanged ideas, and disagreed for fourteen centuries.
Muslims honor Isa (Jesus) (Peace Be Upon Him) as one of the mightiest messengers of ALLAH. The Quran speaks about him at length. Muslims also honor his mother, Maryam (Mary), and consider her among the greatest women who ever lived. An entire chapter of the Quran is named after her.
At the same time, Islam and Christianity differ on central questions — especially the nature of Isa (Jesus) (Peace Be Upon Him), the Trinity, the crucifixion, and whether Muhammad ﷺ (Peace Be Upon Him) is the final Messenger. These differences are real and they matter. This article presents them honestly and without hostility.
This is a comparative overview, not a debate. The goal is understanding.
A Respectful Starting Point
In Islamic sources, Jews and Christians are referred to as the People of the Book — communities who received earlier revelation from ALLAH. The Quran calls them to the shared foundation of worshiping ALLAH alone.
“Say: O People of the Scripture, come to a word that is just between us and you — that we worship none but ALLAH, and that we associate nothing with Him, and that none of us takes others as lords besides ALLAH.”
This invitation establishes the foundation of this discussion: common ground in worshiping the One God, and honest acknowledgment of where beliefs differ.
Respect does not mean pretending all beliefs are the same. Honesty does not require harshness. Both are possible together.
Shared Themes
Islam and Christianity share genuine common ground, though the specific meanings often differ in important ways.
“Say: We have believed in ALLAH and in what was revealed to us and what was revealed to Ibrahim, Ismail, Ishaq, Yaqub, and the Descendants, and in what was given to Musa and Isa and to the prophets from their Lord. We make no distinction between any of them, and we are Muslims in submission to Him.”
Shared areas between Islam and Christianity — with important distinctions:
- Belief in one God — though Islamic Tawheed and Trinitarian theology differ fundamentally
- Belief in revelation and scripture — though which scriptures are authoritative differs
- Belief in prophets and messengers — though the specific prophets recognized and how differ
- Belief in angels — affirmed in both traditions
- Belief in moral responsibility — both traditions teach accountability before God
- Belief in the Hereafter — both affirm life after death, reward, and punishment
- Honor for Isa (Jesus) (Peace Be Upon Him) and Maryam (Mary) (Peace Be Upon Her) — though the nature of this honor differs significantly
Important Distinction
Do not say that Muslims and Christians believe identical things about the topics above. The shared themes are real, but their meanings differ in ways that matter. This article presents those differences honestly.
Who Is Isa (Jesus) in Islam?
Isa (Jesus) (Peace Be Upon Him) holds a distinguished place in Islam. He is one of the five greatest messengers of ALLAH — the Ulul Azm prophets of firm resolve — alongside Nuh (Noah), Ibrahim (Abraham), Musa (Moses), and Muhammad ﷺ (Peace Be Upon Them All).
“When the angels said: O Maryam, indeed ALLAH gives you good news of a word from Him, whose name will be the Messiah, Isa the son of Maryam — distinguished in this world and the Hereafter and among those brought near to ALLAH.”
“The Messiah, son of Maryam, was no more than a messenger. Messengers had come and gone before him. His mother was a woman of truth. Both of them used to eat food. See how We make the signs clear to them, then see how they are turned away.”
What Muslims believe about Isa (Jesus) (Peace Be Upon Him):
- He was a real prophet and messenger sent by ALLAH
- He was born miraculously to Maryam (Mary), without a human father
- He performed miracles by ALLAH's permission — healing, restoring sight, and raising the dead
- He called the Children of Israel to worship ALLAH alone
- He was given the Injil — revelation and guidance from ALLAH
What Muslims do not believe:
- Muslims do not believe Isa (Jesus) (Peace Be Upon Him) is ALLAH or the Son of ALLAH in a divine sense
- Muslims do not believe worship of Isa is permitted
- Muslims do not believe he died on the cross
“He said: Indeed, I am the servant of ALLAH. He has given me the Scripture and made me a prophet. And He has made me blessed wherever I am and has enjoined upon me prayer and charity as long as I live.”
Maryam, the Mother of Isa (Peace Be Upon Him)
Maryam (Mary) is one of the most honored women in Islamic tradition. The Quran affirms her purity, her devotion, and her chosen status.
“And when the angels said: O Maryam, indeed ALLAH has chosen you and purified you and chosen you above the women of the worlds.”
“She said: How can I have a boy when no man has touched me, and I have not been unchaste? He said: Thus it will be. Your Lord says: It is easy for Me. And We will make him a sign to the people and a mercy from Us. And it is a matter already decreed.”
Surah Maryam — the nineteenth chapter of the Quran — is named after her and tells her story in detail. She appears by name more times in the Quran than in the New Testament.
Tawheed and the Trinity
At the foundation of Islamic theology is Tawheed — the absolute oneness of ALLAH. ALLAH is One, without partner, without division, without child, and nothing resembles Him.
“Say: He is ALLAH, the One. ALLAH, the Eternal, Absolute. He begets not, nor was He begotten. And there is none comparable to Him.”
Most mainstream Christians affirm the doctrine of the Trinity — the teaching that God exists as one Being in three persons: the Father, the Son, and the Holy Spirit. This doctrine is held broadly across Catholic, Orthodox, and most Protestant denominations, though its precise theological formulation has a long and detailed history within Christianity itself.
On Describing the Trinity Fairly
The Trinity should be described as mainstream Christians themselves describe it: one God in three persons, not three separate gods. Islam disagrees with the Trinity, but that disagreement should be stated clearly — not by misrepresenting what Christians actually believe.
Islam rejects the Trinity because Islamic Tawheed holds that ALLAH is absolutely One — without division, partner, or likeness. The Quran addresses this directly:
“O People of the Scripture, do not commit excess in your religion and do not say about ALLAH except the truth. The Messiah, Isa the son of Maryam, was but a messenger of ALLAH and His word which He directed to Maryam and a soul from Him. So believe in ALLAH and His messengers. And do not say: Three. Desist — it is better for you. Indeed, ALLAH is but one God. Exalted is He above having a son.”
“They have certainly disbelieved who say that ALLAH is the Messiah, the son of Maryam. But the Messiah himself said: O Children of Israel, worship ALLAH, my Lord and your Lord. Indeed, whoever associates others with ALLAH — ALLAH has forbidden him Paradise, and his refuge is the Fire.”
Did Isa (Jesus) (Peace Be Upon Him) Claim to Be God?
This question is discussed extensively between Christians and Muslims, and the two traditions interpret the statements of Isa (Jesus) (Peace Be Upon Him) very differently.
Muslims believe Isa (Jesus) (Peace Be Upon Him) was a servant and messenger of ALLAH. The Quran quotes Isa (Peace Be Upon Him) as calling himself the servant of ALLAH and attributing all his knowledge and action to ALLAH:
“And when ALLAH will say: O Isa, son of Maryam, did you say to the people: Take me and my mother as deities besides ALLAH? He will say: Exalted are You. It was not for me to say what I had no right to say. If I had said it, You would have known it.”
Many Christians point to passages in the New Testament — particularly in the Gospel of John — in support of Isa (Jesus) (Peace Be Upon Him)'s divine identity. For Muslims, some statements recorded in the Gospels that describe Isa (Jesus) (Peace Be Upon Him) in monotheistic terms are significant to note. These include passages where Isa (Jesus) addresses God directly as the only true God, where he repeats the Jewish declaration of monotheism, and where he describes himself as ascending to his Father and God.

Muslims do not claim to be the authoritative interpreters of Christian scripture. This section summarizes comparative observations, not definitive Christian doctrine.
The Crucifixion and Resurrection
The crucifixion and resurrection of Isa (Jesus) (Peace Be Upon Him) are central to most Christian theology — the belief that Isa (Jesus) (Peace Be Upon Him) died as an atoning sacrifice and rose from the dead, making salvation available to humanity.
Islam does not accept the Christian account of the crucifixion. The Quran addresses this directly:
“And their saying: Indeed, we have killed the Messiah, Isa the son of Maryam, the Messenger of ALLAH. But they did not kill him, nor did they crucify him; but it was made to appear so to them. And indeed, those who differ over it are in doubt about it. They have no knowledge of it except the following of assumption. And they did not kill him for certain. Rather, ALLAH raised him to Himself. And ever is ALLAH Exalted in Might and Wise.”
The Islamic position is that Isa (Jesus) (Peace Be Upon Him) was not killed on the cross. ALLAH raised him. Muslims should not speculate beyond this Quranic statement.
A Note on This Difference
This is one of the most significant differences between Islam and Christianity. Christians understand the crucifixion as the center of salvation history. Muslims affirm that ALLAH protected His messenger and raised him. This difference should be stated clearly and calmly — it does not require hostility from either side.
On Christian Scripture Referenced Here
Christian scripture passages about the crucifixion and resurrection are referenced in the spec for comparative context (1 Corinthians 15:3–4, Matthew 27–28, Luke 24). These are not quoted here because exact translations have not been verified. (TODO: verify before adding any direct quotation from these passages.)
Salvation in Islam and Christianity
The question of how a person is saved or forgiven before ALLAH is answered differently in Islam and Christianity.
In Islam, salvation rests on:
- Sincere Tawheed — believing in ALLAH alone and worshiping Him alone
- Repentance (Tawbah) — returning to ALLAH sincerely after sin
- Righteous deeds — prayer, charity, obedience, and good character
- ALLAH's mercy — ultimately, no one enters Paradise purely by their own deeds
“Say: O My servants who have transgressed against themselves — do not despair of the mercy of ALLAH. Indeed, ALLAH forgives all sins. Indeed, it is He who is the Forgiving, the Merciful.”
“By time, indeed mankind is in loss — except for those who have believed and done righteous deeds and advised each other to truth and advised each other to patience.”
“Say: I am only a man like you, to whom it has been revealed that your god is one God. So whoever hopes to meet his Lord — let him do righteous work and not associate anyone in the worship of his Lord.”
The Prophet ﷺ (Peace Be Upon Him) said: "No one of you will enter Paradise by his deeds alone." They said: Not even you, O Messenger of ALLAH? He said: "Not even I, unless ALLAH covers me with His grace and mercy."
In Christianity, most traditions teach that salvation comes through faith in Isa (Jesus) (Peace Be Upon Him) as Lord and Savior, particularly through his death and resurrection as an atonement for sin. Different Christian traditions emphasize different aspects — some stress faith alone (sola fide), others emphasize faith alongside works and sacraments. There is genuine theological diversity within Christianity on this point.

The Bible, the Injil, and the Quran
Muslims believe ALLAH revealed the Injil — the original Gospel — to Isa (Jesus) (Peace Be Upon Him). It was guidance and light, confirming the Torah before it.
“And We sent in their footsteps Isa the son of Maryam, confirming what came before him of the Torah. And We gave him the Injil, in which was guidance and light, and confirming what preceded it of the Torah, as guidance and instruction for the righteous.”
Muslims do not believe that the current New Testament is identical in every word to the original Injil revealed to Isa (Peace Be Upon Him). However, claims about the textual history of scripture are a subject of careful scholarly inquiry and should not be stated carelessly.
Handle This With Care
Muslims should not make sweeping claims about biblical manuscript history without specific scholarly support. Broad generalizations about corruption or change require evidence. Making exaggerated claims is both inaccurate and unhelpful. (TODO: verify any specific historical or manuscript claims with academic primary-source review before publication.)
Muslims believe the Quran is the final preserved revelation from ALLAH, confirmed and protected:
“Indeed, it is We who sent down the Reminder and indeed, We will be its guardian.”
“And We have revealed to you the Scripture in truth, confirming what came before it of the Scripture and as a guardian over it. So judge between them by what ALLAH has revealed and do not follow their desires away from what has come to you of the truth.”
Muhammad ﷺ and Isa (Jesus) (Peace Be Upon Him)
Muslims believe Muhammad ﷺ (Peace Be Upon Him) is the final Messenger — and that his arrival was foretold by earlier prophets, including Isa (Jesus) (Peace Be Upon Him):
“And when Isa the son of Maryam said: O Children of Israel, indeed I am the messenger of ALLAH to you, confirming what came before me of the Torah and bringing good news of a messenger to come after me, whose name is Ahmad.”
“Muhammad is not the father of any of your men, but he is the Messenger of ALLAH and the seal of the prophets. And ever is ALLAH, of all things, Knowing.”
Following Muhammad ﷺ (Peace Be Upon Him) is not, in Islam, a rejection of Isa (Jesus) (Peace Be Upon Him). Muslims believe that following the final guidance of ALLAH is the fullest form of obedience to all the prophets. The prophets carried one consistent message — worship ALLAH alone — and Muhammad ﷺ (Peace Be Upon Him) sealed and completed it.

Common Questions
Do Muslims believe in Isa (Jesus) (Peace Be Upon Him)?
Yes. Muslims believe Isa (Jesus) (Peace Be Upon Him) was a real prophet and messenger of ALLAH. He was born miraculously to Maryam (Mary) (Peace Be Upon Her), performed miracles by ALLAH's permission, and called people to worship ALLAH alone. Believing in him is part of Islamic faith.
Do Muslims love Isa (Jesus) (Peace Be Upon Him)?
Yes. In Islam, honoring and loving the messengers of ALLAH is part of faith. Muslims do not worship Isa (Jesus) (Peace Be Upon Him), but they honor and respect him deeply as one of the greatest messengers.
Do Muslims believe Isa (Jesus) (Peace Be Upon Him) is God?
No. Muslims believe ALLAH is absolutely One, without partner, child, or equal. Isa (Jesus) (Peace Be Upon Him) was a prophet and messenger — one of the greatest — but not divine.
Do Muslims believe in the Bible?
Muslims believe ALLAH revealed the Injil to Isa (Jesus) (Peace Be Upon Him) as guidance and light. Muslims do not believe the current New Testament is identical in every word to that original revelation. The Quran is understood as the final and preserved word of ALLAH.
What is the Injil?
The Injil is the revelation ALLAH gave to Isa (Jesus) (Peace Be Upon Him). The Quran mentions it several times as guidance and light, confirming the Torah before it. Muslims respect it as original revelation from ALLAH.
Do Muslims and Christians worship the same God?
Muslims worship ALLAH — the One God, Creator of all things, the God of Ibrahim (Abraham) (Peace Be Upon Him). Islam calls all people, including Christians, to pure monotheism (Tawheed). There are genuine shared roots in the Abrahamic tradition. However, Islamic Tawheed is fundamentally different from Trinitarian Christian theology. This question deserves honest engagement rather than a simple yes or no. Muslims call Christians to the pure worship of ALLAH alone.
Why do Muslims reject the Trinity?
Because Islamic Tawheed holds that ALLAH is absolutely One — without division, partner, or anything comparable. The Quran addresses Trinitarian claims directly and calls it an excess. ALLAH has no child and no partner.
What does Islam say about salvation?
Salvation in Islam is through sincere faith in ALLAH alone (Tawheed), repentance, righteous deeds, and ultimately ALLAH's mercy. The Prophet ﷺ (Peace Be Upon Him) taught that no one enters Paradise purely by their deeds — ALLAH's mercy is essential. ALLAH is the Most Forgiving, the Most Merciful.
Can Muslims be respectful to Christians while disagreeing?
Yes. Respecting Christians as people is a duty in Islam. Honest disagreement about theology is fair and necessary. The Quran itself calls the People of the Book to a common word — not to conflict. Disagreement should not become contempt.
What should a Christian study first about Islam?
Start with Tawheed — the Oneness of ALLAH. Then read about prophethood in Islam, the message all prophets carried, and why Muslims believe the Quran is the final revelation. The Foundations section on this website is a good starting point.
What Muslims Should Avoid
- Do not mock Christian beliefs, rituals, or scripture.
- Do not insult Isa (Jesus) (Peace Be Upon Him) or Maryam (Mary).
- Do not misquote or misrepresent the Bible.
- Do not use weak arguments or exaggerated claims.
- Do not attack Christians as people.
- Do not speak about Christian theology without knowledge.
- Do not turn comparison into a contest to win.
- Do not treat dawah as debate. It is an invitation to truth with wisdom and good character.
What Christians Should Understand About Islam
- Islam honors Isa (Jesus) (Peace Be Upon Him) as one of the greatest messengers of ALLAH.
- Islam honors Maryam (Mary) as one of the greatest women who ever lived.
- Islam calls all people to pure worship of ALLAH alone — not to abandon sincerity, but to examine Tawheed carefully.
- Islam does not ask Christians to reject the goodness they have. It asks them to consider whether final guidance has come through Muhammad ﷺ (Peace Be Upon Him).
- Muhammad ﷺ (Peace Be Upon Him) did not come to erase what came before. He came to complete and confirm the original message of all the prophets.
- The best way to understand Islam is to read the Quran with an open heart.
