Ishmael: The Rightful Heir of the Abrahamic Covenant – Revisiting Biblical Circumcision and Lineage

The Abrahamic covenant stands as a foundational pillar in the sacred histories of Judaism, Christianity, and Islam. Central to this covenant is the rite of circumcision, instituted by God as a binding sign between Himself and Abraham’s descendants.

Traditionally, Jewish and Christian interpretations assert that Isaac, the son born to Abraham and Sarah, is the rightful heir through whom this covenant is fulfilled.

However, a careful reexamination of the biblical chronology challenges this assumption. This article argues that Ishmael, not Isaac, was the first and only son to receive the covenantal sign alongside Abraham himself—prior to Isaac’s birth—thereby establishing Ishmael as the sole and true heir of the original Abrahamic covenant. By exploring the timing, recipients, and implications of circumcision in Genesis 17 and 21, this piece invites readers to reconsider long-held views and appreciate the overlooked centrality of Ishmael in the divine covenant.

1. The Biblical Basis for Circumcision as a Covenant

The Bible establishes circumcision as the sign of the covenant between God and Abraham:

Genesis 17:9–11:

“Then God said to Abraham, ‘As for you, you must keep my covenant, you and your descendants after you for the generations to come. This is my covenant with you and your descendants after you, the covenant you are to keep: Every male among you shall be circumcised… it will be the sign of the covenant between me and you.’”
Here, circumcision is the definitive sign of the Abrahamic covenant.

2. The Timing of Circumcision Before Isaac’s Birth

The Bible affirms that circumcision was performed before Isaac was born:

Genesis 17:23–26:

“On that very day Abraham took his son Ishmael and all those born in his household or bought with his money, every male in his household, and circumcised them, as God told him… Abraham was ninety-nine years old when he was circumcised, and his son Ishmael was thirteen.”
At this critical juncture, only Abraham and Ishmael were Abraham’s natural descendants to receive the sign of the covenant. Isaac had not yet been born.

3. Ishmael as the Sole and True Heir of the Abrahamic Covenant

This sequence of events reveals that:
Circumcision is the outward and binding sign of the Abrahamic covenant.
Ishmael was the only son of Abraham present to receive this sign alongside him.
All others circumcised at that time were household members and servants—not Abraham’s direct offspring.
Therefore, Ishmael alone stands as the true and sole heir of the Abrahamic covenant, sharing this foundational covenantal sign with Abraham himself.

4. Isaac as Merely a Participant Like Other Household Members

When Isaac was born, he too was circumcised on the eighth day (Genesis 21:4). However, this circumcision occurred after the covenant was already established through Abraham and Ishmael. Like the other members of Abraham’s household, Isaac simply entered into an existing covenantal practice rather than establishing or uniquely embodying it.

In this understanding:
Isaac’s circumcision parallels that of Abraham’s other household members.
He was brought into the covenantal sign but did not share in the original covenantal enactment alongside Abraham.
Thus, Isaac is seen merely as a participant in the Abrahamic covenant, not as its unique heir.

5. Distinction from the Sinai Covenant

The Sinai covenant was revealed exclusively to the descendants of Isaac through Jacob (Israel), establishing a separate covenantal framework for the Israelites.

In contrast, the original Abrahamic covenant—established through circumcision before Isaac’s birth—finds its complete and exclusive fulfillment in Ishmael, who was the first to embody and share this sign with Abraham.

6. Challenging Traditional Jewish and Christian Views

Traditionally, Jewish and Christian interpretations place Isaac as the sole heir of the Abrahamic covenant. However, this argument radically reorients that view:
Ishmael alone shares the covenantal enactment with Abraham.
Isaac, like the other household members, enters a covenantal practice already established.
Therefore, Ishmael alone emerges as the true and rightful heir of the Abrahamic covenant.

Summary of the Articulation

Circumcision, the outward sign of the Abrahamic covenant, was first performed on Abraham and Ishmael before Isaac was born. This historical reality establishes that while Isaac and others in Abraham’s household were participants in the sign of the covenant, only Ishmael shared in the covenant’s original establishment and thus stands as its true and exclusive heir. In this perspective, Ishmael’s role transcends mere participation—he alone embodies the Abrahamic covenant in its full and foundational form.

Hajj as the Fulfillment of Abrahamic Prophecy

Torah, Genesis 22 verse 18, reads:

“And in thy seed shall all the nations of the earth be blessed; because thou hast obeyed my voice.”

It is believed the event of the Hajj in Mecca is the fulfillment of the biblical prophecy of Genesis 22 verse 18. According to the Islamic belief, Abraham offered Ishmael, not Isaac, as a sacrifice to God, emphasizing Ishmael’s role in fulfilling God’s covenant with Abraham. The event of Hajj proves that God made a covenant with Abraham through Hagar and Ishmael rather than Sarah and Isaac. How is this viewpoint presented?

The viewpoint that the Hajj in Mecca is a fulfillment of the biblical prophecy of Genesis 22 verse 18, and represents a covenant made by God with Abraham through Hagar and Ishmael, rather than Sarah and Isaac, is articulated based on several key aspects of Islamic belief and interpretation of religious texts:

1. Prophecy of Genesis 22 verse 18: The verse in Genesis states:

“And in thy seed shall all the nations of the earth be blessed; because thou hast obeyed my voice.”
Some interpret this as a prophecy that is fulfilled through the descendants of Ishmael, Abraham’s son with Hagar. The Islamic narrative holds that it was Ishmael, not Isaac, who was offered by Abraham as a sacrifice to God. This signifies Ishmael’s importance in the fulfillment of God’s covenant with Abraham. The Hajj, as a major Islamic ritual commemorating the actions of Abraham and Ishmael, is seen as a manifestation of this blessing.

2. The Hajj and Ishmael’s Legacy: In Islamic tradition, the Hajj includes rituals that are believed to commemorate the life and trials of Abraham and his son Ishmael. The ritual of Sa’i, where pilgrims travel back and forth between the hills of Safa and Marwah, is seen as a re-enactment of Hagar’s desperate search for water for her infant son Ishmael. According to Islamic belief, the well of Zamzam originated to rescue baby Ishmael.

3. The Kaaba and Islamic Tradition: The Kaaba in Mecca, which is the focal point of the Hajj, is believed in Islamic tradition to have been built by Abraham and Ishmael as a house of worship to the one true God. This act of establishing monotheism in the region is viewed as a key part of fulfilling God’s covenant with Abraham.

4. Universal Blessing and Unity of Humankind: The Hajj is seen as a fulfillment of God’s promise to bless all nations through Abraham’s descendants. The gathering of millions of Muslims from diverse nations during Hajj is viewed as a symbol of this blessing and the unity of humankind under God’s guidance.

5. Continuity of Abrahamic Tradition: The Hajj is also seen as a continuation and fulfillment of the Abrahamic tradition of monotheism. This perspective posits that Islam, as the final revelation in the Abrahamic tradition, fulfills and perfects earlier revelations given to Jews and Christians.

This viewpoint is part of the broader Islamic interpretation of religious history, which sees Islam as both a continuation and a completion of the monotheistic tradition established by Abraham.

Interpolation in the Torah from an Islamic viewpoint

Here is how the Jewish scribe manipulated Ishmael’s story:

The age of Ishmael at the time of his departure from Abraham’s house.
Abraham’s son, who was offered as a sacrifice.
Some Islamic scholars suspect that the scribes tampered with the story of Hagar and Ishmael in the Torah. It is argued that Genesis 21, verses 9 to 10, may have been added later because Ishmael and Hagar had already left Abraham’s house long before Isaac was born, with Ishmael being an infant according to Islamic tradition.

Similarly, some question whether Genesis 22, verse 2, could refer to Ishmael, since Isaac had never been Abraham’s only son, whereas Ishmael had been for fourteen years before Isaac was born. How is this Islamic viewpoint presented?

The Islamic perspective on the stories of Hagar, Ishmael, and Isaac, as presented in the Torah, differs significantly from the Jewish and Christian narratives. These differences have led some Islamic scholars to question the authenticity of certain Biblical passages, suggesting possible later additions or alterations.

In the Islamic tradition, Hagar and Ishmael’s story is seen through a different lens compared to the Biblical account. According to Islamic belief, Ishmael was an infant when he and his mother Hagar were left in the desert, which contrasts with the Biblical narrative where Ishmael is depicted as a young boy during this event. Some Islamic scholars argue that certain verses in Genesis, such as Genesis 21:9-10, might have been added later, as they imply that Ishmael was older and capable of mocking Isaac, which would not align with the Islamic timeline where Ishmael had already left before Isaac’s birth.

The question of who was the intended son of sacrifice is another point of divergence. In the Quran, it is generally believed that Ishmael was the son whom Abraham was commanded to sacrifice, whereas the Bible identifies Isaac as the intended sacrifice. This discrepancy has led some Islamic scholars to suggest that Genesis 22, verse 2, which refers to Isaac as Abraham’s “only son,” might be inaccurate, as Ishmael was Abraham’s firstborn and was his only son for fourteen years before Isaac’s birth. The argument is that the description of Isaac as the “only son” could have been a later addition to emphasize Isaac’s significance in the Jewish tradition.

Islamic narratives emphasize the significance of Ishmael and his descendants, linking them to the lineage of the Prophet Muhammad. The Islamic tradition holds that Abraham and Ishmael together built the Kaaba in Mecca, a central element in Islamic faith, which is not mentioned in the Bible. The Quran and Islamic teachings often highlight the spiritual and prophetic roles of both Ishmael and Isaac, but with a focus on Ishmael’s role in the lineage leading to Islam.

Conclusion

The Islamic viewpoint on the story of Hagar and Ishmael in the Torah is characterized by skepticism towards the authenticity of certain verses. Islamic scholars argue that the timeline and events described in the Torah may have been altered, and that Ishmael may have been the son referred to in Genesis 22:2 instead of Isaac.

The Symbolism of Eid al-Adha (Feast of the Sacrifice)

What is Eid al-Adha?

Eid al-Adha is the “Feast of the Sacrifice,” commemorating Abraham’s devotion to God, when he intended to sacrifice his son and God provided a lamb to sacrifice instead. It follows the Hajj rituals for pilgrims in Mecca, but is celebrated by all Muslims.

Certain scholars contend that Eid Al Adha in Islam suggests a scribal interpolation in the Torah concerning the son intended for near sacrifice, positing that it is Ishmael rather than Isaac. How is their argument articulated?

Some Islamic scholars argue that Eid al-Adha in Islam points to a scribal interpolation in the Torah regarding which son Abraham was commanded to sacrifice. Their argument for scribal interpolation is articulated as follows:

Islamic tradition holds that it was Ishmael, not Isaac, whom Abraham was commanded to sacrifice. This belief forms the basis for the celebration of Eid al-Adha, one of the most important festivals in Islam.

Scholars who support this view present several arguments:

1. Primacy of Ishmael: They argue that Ishmael, being Abraham’s firstborn son, was the original heir to the covenant and thus the logical choice for such a significant test of faith.

2. Quranic Account: The Quran’s narrative of the sacrifice does not explicitly name the son, but contextual evidence and Islamic tradition point to Ishmael. This interpretation stems from the chronological events presented in the Quran, indicating that the promise of Isaac’s birth occurred after the narrative of the sacrifice, thereby suggesting that Ishmael was the son mentioned in that context.

3. Historical Context: These scholars suggest that ancient Israelite scribes may have altered the original text to emphasize Isaac’s role, shifting the focus away from Ishmael to establish a stronger theological foundation for Israelite claims.

4. Geographical Inconsistencies: They point out that the biblical account mentions Mount Moriah, while Islamic tradition places the event near Mecca, where Ishmael and Hagar settled.

5. Linguistic Analysis: Some argue that careful examination of the original Hebrew text reveals inconsistencies that suggest later editing.

If this interpretation is accepted, it would have significant implications: It would challenge the traditional Jewish and Christian understanding of the Abrahamic covenant.

It would support the Islamic view of Ishmael as a central figure in the Abrahamic narrative. It would reinforce the Islamic belief in the Quran as a correction to earlier scriptures.

What theological reasoning do Islamic scholars offer to explain how Abraham’s near sacrifice of Ishmael, instead of Isaac, supports the prophethood of Muhammad?

According to Islamic tradition and theology, the near sacrifice of Ishmael by Abraham, rather than Isaac, provides support for the prophethood of Muhammad in several key ways:

Judaism, Christianity, and Islam all trace their spiritual lineage to Abraham as a shared patriarch. The story of Abraham’s willingness to sacrifice his son at God’s command is seen as a supreme test of faith in all three traditions. By identifying the son as Ishmael rather than Isaac, Islam establishes a direct link between Abraham and Muhammad through Ishmael.

The Quran in Surah 37 recounts the story of Abraham’s willingness to sacrifice his son out of obedience to God. Despite not explicitly naming the son, the Quran places the narrative of the sacrifice before the announcement of Isaac’s birth, which some interpret as an indication that Ishmael was the one sacrificed. This Quranic account is seen as affirming Ishmael’s role.

Islamic tradition holds that Muhammad is a direct descendant of Ishmael. The legitimacy and authenticity of Muhammad’s prophethood is thus connected to this lineage going back to Abraham through Ishmael. Ishmael’s willingness to be sacrificed is viewed as a significant event that foreshadows the prophethood of Muhammad, which holds a central role in the religion.

Muslims believe the Quran is the final, unaltered word of God as revealed to Muhammad, arguing that earlier scriptures like the Torah and Bible have been changed over time. In this view, the Quran corrects these alterations, and its indication that Ishmael was the sacrificial son is seen as the accurate version of the story. This affirms Muhammad’s role in restoring the original monotheistic message.

While acknowledging the prophets of Judaism and Christianity, Islam considers Muhammad to be the final prophet who came to restore the pure monotheistic faith and correct deviations that had entered the earlier religions. The story of Ishmael’s near-sacrifice is thus seen as part of this corrective prophetic message continuing through Muhammad.

In summary, the Islamic theological argument is that the identification of Ishmael as the son Abraham was commanded to sacrifice establishes a direct link between Abraham, Ishmael, and Muhammad, supporting the legitimacy of Muhammad’s prophethood as a continuation of the Abrahamic lineage and monotheistic message that was preserved intact through Ishmael and fully restored in the revelation of the Quran to Muhammad. The Ishmael narrative reinforces Muhammad’s prophetic authority for Muslims.
