The Abrahamic religions, namely Islam, Christianity, and Judaism, share a common monotheistic foundation, tracing their origins back to Prophet Abraham. All three religions emphasize the worship of one God, a principle known as Tawhid in Islam, and adhere to a set of divine laws and moral codes revealed through prophets . Despite these fundamental similarities, they exhibit distinct differences in their specific legal codes, rituals, and interpretations of divine revelation, particularly concerning the finality of prophethood and the nature of God .
Islam, in its general sense, is understood as the submission to God through monotheism, obedience to His commands, and freedom from polytheism. This general concept of Islam is considered the religion of all prophets and their followers, from the first of creation to the last . However, after the advent of Prophet Muhammad, Islam in its specific sense refers to the religion revealed to him, which abrogated previous laws and became the universally binding faith. Adherence to the specific laws and teachings of Prophet Muhammad is now considered essential for salvation .

The Unity of Divine Religion and the Diversity of Laws
The fundamental principle underlying the relationship between Islam, Christianity, and Judaism is the concept that the religion of God, in its essence, is one across all times and places. This singular religion is Islam, which, in its general sense, signifies submission to God through Tawhid (monotheism), obedience to His commands, and freedom from Shirk (polytheism) . This overarching definition of Islam applies to all prophets and their followers, from the earliest to the latest. Thus, every prophet called their people to this fundamental submission to God, and anyone who followed them in this regard was considered a Muslim .
The unity of religion among prophets is explicitly stated in the Prophetic tradition: "We, the community of prophets, our religion is one," and "Prophets are brothers from different mothers; their mothers are diverse, but their religion is one" . This indicates that while the core belief in the Oneness of God and submission to Him remained constant, the specific Sharia (divine laws or legal codes) varied according to the needs and circumstances of different communities in different eras . The Quran states, "To each of you We have appointed a law and a way" (Quran 5:48), illustrating that God prescribed laws suitable for each prophet's people and their interests .
However, with the advent of Prophet Muhammad (peace be upon him), the previous laws were abrogated, and his religion became the universally binding faith. Therefore, it is not permissible for anyone to remain on a previous religion after the revelation of Islam to Prophet Muhammad . This specific form of Islam, encompassing the Quranic law, is what is understood as Islam today when the term is used without qualification .
Core Similarities: Monotheism and Prophethood
All Abrahamic religions share the foundational belief in one God, the Creator and Sustainer of the universe. This principle of Tawhid is the essence of Islam, and it was the central message of all prophets, including Noah, Abraham, Moses, and Jesus . The Quran emphasizes that God sent messengers to every nation with the command to "Worship Allah and avoid Taghut (false deities)" (Quran 16:36) and "We did not send any messenger before you except that We revealed to him that there is no deity except Me, so worship Me" (Quran 21:25) .
The stories of various prophets in the Quran explicitly show their adherence to Islam in its general sense:
Noah declared, "And I was commanded to be among the Muslims" (Quran 10:72) .
Abraham and Ishmael prayed, "Our Lord, make us Muslims [in submission] to You and from our descendants a Muslim nation [in submission] to You" (Quran 2:128), and Abraham himself said, "I have submitted to the Lord of the worlds" (Quran 2:131) .
Moses told his people, "O my people, if you have believed in Allah, then rely upon Him, if you should be Muslims" (Quran 10:84) .
Jesus's disciples (al-Hawariyyun) affirmed, "We have believed in Allah, and testify that we are Muslims" (Quran 3:52) .
This consistent message across prophets highlights the shared core of monotheistic worship and submission to God's will. The Quran also explicitly refutes the idea that Abraham was a Jew or a Christian, stating, "Abraham was neither a Jew nor a Christian, but he was a Hanif [monotheist] and a Muslim, and he was not of the polytheists" (Quran 3:67) . This underscores the Islamic belief that the original religion of Abraham and all prophets was pure monotheism, free from later innovations.
Another shared aspect is the belief in prophethood and divine revelation through sacred texts. Muslims believe in all the prophets mentioned in the Quran, including those revered in Judaism and Christianity, such as Moses and Jesus, and acknowledge the divine origin of the Torah and the Gospel in their original forms . The six articles of faith in Islam—belief in Allah, His angels, His books, His messengers, the Day of Judgment, and divine decree (Qadar)—are considered fundamental and have been agreed upon by all messengers and divine laws . Disbelief in any of these articles, or in any of the messengers, is considered a departure from the sphere of faith .
Key Differences: Specific Laws, Finality of Prophethood, and Innovations
While the fundamental religion (Islam in its general sense) is one, the Sharia (specific laws and methodologies) varied among prophets . God legislated for each nation what suited its condition and time, then abrogated certain laws for another nation as needed . For example, the obligation of observing the Sabbath for the Children of Israel was later abrogated and replaced with Friday for Muslims .
The most significant difference arises with the advent of Prophet Muhammad. His message is considered universal, encompassing all humanity and extending until the Day of Judgment, abrogating all previous laws . Therefore, adherence to the specific teachings and laws brought by Prophet Muhammad is now mandatory for all people . Those who cling to abrogated laws, such as Jews and Christians, are considered to have disbelieved because they adhere to a superseded law .
Furthermore, Islam identifies specific innovations and deviations in Christianity and Judaism. For instance, the Quran criticizes the Christians for taking their rabbis and monks as lords besides God, and for associating Jesus and his mother with divinity, stating that they were commanded only to worship one God . Jesus himself denied commanding people to worship him or his mother, affirming that he only told them to worship God, his Lord and their Lord . This highlights the Islamic rejection of the concept of divinity for prophets or saints, emphasizing that taking angels or prophets as lords constitutes disbelief .
Another point of divergence is the concept of monasticism (Rahbaniyyah). The Quran mentions that Christians "invented monasticism; We did not prescribe it for them except as a means to seek Allah's pleasure, but they did not observe it with due observance" (Quran 57:27) . This indicates that monasticism was an innovation by the Christians themselves, not a divine command, even if their initial intention was to seek God's pleasure . The Prophet Muhammad explicitly stated, "There is no monasticism in Islam" .
The concept of Shirk (associating partners with God) is a critical distinction. While the core message of all prophets was to worship God alone, later generations, particularly among the People of the Book, introduced practices that Islam considers polytheistic . This includes invoking intermediaries, seeking intercession from others besides God, or attributing divine qualities to creation . The Quran explicitly condemns those who claim to believe in God but associate partners with Him, stating that their belief in God as the Creator and Sustainer does not benefit them if they also worship others . This is exemplified by the polytheists who would acknowledge God as the Creator but still worship idols as intercessors .
Furthermore, the Quran highlights that the People of the Book (Jews and Christians) recognized Prophet Muhammad as they recognized their own children, indicating their knowledge of his prophethood from their scriptures, yet many concealed this truth out of envy and arrogance . This deliberate concealment and rejection of the final prophet is considered a significant deviation.
Conclusion
Islam, Christianity, and Judaism are interconnected as Abrahamic religions, sharing a common lineage through Prophet Abraham and a foundational belief in monotheism. The core message of all prophets, which is submission to the One God (Islam in its general sense) and the rejection of polytheism, remains constant. However, the specific divine laws and practices (Sharia) varied across different prophetic dispensations. With the advent of Prophet Muhammad, his message became the final and universal law, superseding all previous ones. Key differences therefore lie in the specific legal codes, the finality of prophethood, and the Islamic critique of certain practices and theological developments within Christianity and Judaism, such as monasticism and the association of partners with God, which are considered deviations from pure monotheism. Adherence to the specific teachings of Prophet Muhammad is deemed essential for salvation in the current era.
