Heir to Abraham: Isaac vs. Ishmael

The phrase "Heir to Abraham: Isaac vs. Ishmael" pertains to the biblical narrative surrounding Abraham, who is regarded as the progenitor of both Isaac and Ishmael. In the biblical account, God assures Abraham that he will have a son, leading to the birth of two sons: Isaac, born to his wife Sarah, and Ishmael, born to his servant Hagar.

The competition between Isaac and Ishmael arises from their respective positions as heirs to Abraham's legacy. Within Jewish tradition, Isaac is recognized as the legitimate heir and the primary recipient of God's covenant with Abraham, while Ishmael is frequently depicted as an outsider or a rejected figure.

Conversely, Islamic tradition perceives Ishmael as a fruit of Abraham, wheras Isaac is considered a divine gift given to Abraham and Sarah during their later years, due to Abraham's obedience in leaving the infant Ishmael and his mother in the desert near the Kaaba (the house of God), as well as his willingness to sacrifice Ishmael.

I seek clarification regarding the interpretation of this argument.

In the Islamic tradition, Ishmael is regarded as a symbol of Abraham's initial struggle and test of faith, while Isaac represents the ultimate reward for his unwavering obedience to God. The narrative of Abraham leaving infant Ishmael and his mother in the desert near the Kaaba illustrates Abraham's trust in God's plan, even when confronted with difficult decisions.

Abraham's readiness to sacrifice Ishmael further underscores his complete submission to God's will, as he was willing to relinquish the most precious thing in his life without hesitation. This act of devotion holds great significance in Islamic teachings and serves as a compelling example of faith and obedience.

As a reward for Abraham’s steadfastness and willingness to follow God’s commands — both in leaving infant Ishmael and Hagar in the desert and in his willingness to sacrifice Ishmael — God granted Abraham and Sarah a miraculous gift: the birth of Isaac in their old age.

This divine blessing signified God’s recognition of Abraham’s faith and further cemented his role as a patriarch of monotheistic faith, with both Ishmael and Isaac becoming the forebears of great nations.

This narrative highlights the interconnected themes of sacrifice, trust, and divine reward, demonstrating that true faith is met with God’s grace and fulfillment of His promises.

The Quran asserts that it rectifies the biblical narrative surrounding Abraham by confirming Ishmael as the son who carried on Abraham's legacy in accordance with the Abrahamic covenant. Additionally, the divine selection of the ancient Israelites and their Hebrew prophets under the Sinai covenant before the advent of Islam is seen as a precursor to the coming of Muhammad, the last Prophet.

Muhammad and the Hebrew prophets

What is the argument put forth by those who support the idea that the prophethood of Muhammad is linked to Hagar's prophecy, which predates the Torah, in contrast to Hebrew prophets who are associated with the Torah? Consequently, Muhammad, in contrast to Hebrew prophets such as Jesus, is not bound by the laws of the Torah.

Supporters of the idea that the prophethood of Muhammad is linked to Hagar's prophecy, which predates the Torah, argue that this connection sets Muhammad apart from Hebrew prophets who are associated with the Torah. Here is a detailed explanation of their argument:

1. Pre-Torah Origins of Hagar's Prophecy

Proponents argue that Hagar's prophecy, as mentioned in Genesis 21, verse 18, predates the Torah given to Moses. This prophecy concerns Hagar's son, Ishmael, who is promised to become a great nation. This predates the formalization of the Torah, which is traditionally attributed to Moses and his time.

2. Reiteration and Fulfillment in Islamic Rituals

The Torah reiterates Hagar's prophecy, but its fulfillment is seen in Islamic practices, particularly the Hajj pilgrimage. The Hajj, which involves rituals connected to Hagar and Ishmael, is viewed as a direct link to their legacy. This pilgrimage is a central practice in Islam, signifying the prophecy's fulfillment and its importance in Islamic tradition.

3. Marginalization by Ancient Israelite Scribes

It is suggested that ancient Israelite scribes attempted to downplay the significance of Hagar and Ishmael due to theological and political reasons. This marginalization aimed to elevate the prominence of Isaac and the Israelite lineage over Ishmael. The argument posits that the biblical narrative was shaped in a way that selectively emphasized aspects favorable to the Israelite lineage.

Contrast with Hebrew Prophets

1. Association with the Torah

Hebrew prophets are closely linked to the Torah, which is seen as the foundation of their prophetic authority. The Torah, given to Moses, contains the laws and ethical teachings that Hebrew prophets were tasked with interpreting and enforcing. This connection establishes a continuous line of prophetic tradition rooted in the Mosaic covenant.

2. Muhammad's Independent Prophetic Lineage

In contrast, Muhammad's prophethood is associated with the Abrahamic covenant through Ishmael, rather than the Mosaic covenant. This distinction is significant in Islamic theology, which views Muhammad's message as a continuation and fulfillment of the Abrahamic faith, independent of the Mosaic laws. This perspective underscores the universality of Muhammad's revelation, intended for all humanity, rather than being confined to the specific legal and ritual practices of the Jewish people.

Theological Implications

1. Universal Prophetic Tradition

By associating Muhammad with a prophecy that predates the Torah, supporters argue that prophetic messages have been universal and ongoing throughout human history. This places Islam within a broader, inclusive prophetic tradition that transcends Jewish ethnic and religious boundaries. It emphasizes the continuity of divine guidance from the time of Abraham through to Muhammad.

2. Distinct Covenants

The argument also highlights the existence of distinct covenants in the Abrahamic religions. While the Hebrew prophets operate under the covenant of Moses and the Sinai revelation, Muhammad is seen as part of the covenant given to Abraham and Ishmael. This theological distinction reinforces the idea that different prophetic traditions are validated by separate covenants within the broader framework of Abrahamic faiths.

In summary, the argument linking Muhammad's prophethood to Hagar's prophecy emphasizes its pre-Torah origins, fulfillment in Islamic Hajj, and the marginalization of Hagar's significance by ancient Israelite scribes. This perspective contrasts Muhammad's universal and independent prophetic lineage with the Hebrew prophets' association with the Torah, highlighting distinct covenants and a broader prophetic tradition.

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.
