Abrahamic Covenant: Analyzing the Perspective of Fulfillment Through Ishmael

There is a belief among Islamic scholars that the Abrahamic covenant, fulfilled through Ishmael instead of Isaac, entails the promise of the land from the Nile River to the great river of Euphrates, along with the blessing to all nations through Abraham’s seed.

Those who hold this view argue that God asked Abraham to offer Ishmael, not Isaac. They also contend that the ancient Israelite scribes altered their scriptures.
In contrast, the Israelites are bound by the Sinai covenant, which highlights communal responsibilities and accountability to God and to each other as part of the agreement between God and the Israelites. What is the articulation of their argument?

The argument that the Abrahamic covenant is fulfilled through Ishmael rather than Isaac involves several key points articulated by those who support this view. Here is a summary and analysis of their arguments:

1. Promise of the Land: Proponents of this view argue that the promise of the land extending from the Nile River to the Euphrates, as mentioned in Genesis 15, verse 18, was intended for the descendants of Ishmael. They believe that this geographic expanse aligns with the territories historically associated with Islam and Muhammad, who was a descendant of Ishmael.

2. Blessing to All Nations: They interpret the promise of blessings to all nations through Abraham’s seed (Genesis 12, verse 3, and Genesis 22, verse 18) as being fulfilled through Muhammad (Surah 21, verse 107) which reads: “And We have not sent you (O Muhammad) but as a mercy for the unto all beings.” They argue that Islam, preached by Muhammad, has had a significant historical and cultural impact on a global scale, thus fulfilling the promise of being a blessing to all nations.

3. Sacrifice of Ishmael: This argument hinges on the belief that God asked Abraham to offer Ishmael as a sacrifice, rather than Isaac. This is primarily based on Islamic tradition found in the Quran (Surah 37, verses 99 to 113), which states that Abraham was asked to sacrifice his son, and many Muslims believe this son was Ishmael. They argue that this narrative was the original one, which was later altered by Israelite scribes to place Isaac in the position of the sacrificial son.

4. Scriptural Alterations: Supporters of this view contend that ancient Israelite scribes altered the scriptures to reflect Isaac as the chosen son who was to be sacrificed and through whom the covenant would be fulfilled. They believe that these alterations were made to establish and legitimize the Israelite claim to the covenantal promises.

Sinai Covenant Context

The Sinai covenant, distinct from the Abrahamic covenant, focuses on the relationship between God and the Israelites, emphasizing communal responsibilities and accountability. This covenant, given at Mount Sinai, includes the Ten Commandments and a detailed code of laws that govern the moral, religious, and social conduct of the Israelite community. The Sinai covenant underscores the idea that the Israelites are to be a holy nation and a kingdom of priests, dedicated to serving God and adhering to His commandments.


Articulation of Their Argument

Those who argue for the fulfillment of the Abrahamic covenant through Ishmael articulate their position by highlighting these key points:

1. Historical and Geographic Claims: They argue that the promise of the land and blessings align more closely with the historical and geographic realities of Ishmael’s descendants rather than those of Isaac.

2. Islamic Tradition: They cite Islamic scripture and tradition, which they believe preserves the original account of the sacrifice involving Ishmael, rather than Isaac. This account is viewed as being more authentic and less altered than the Hebrew Bible’s version.

3. Critical View of Scripture: They take a critical view of the Hebrew Bible, suggesting that it underwent alterations by Israelite scribes to support their theological and political claims. They argue that these changes were made to establish a narrative that centers on Isaac and his descendants as the primary inheritors of God’s covenant with Abraham.

4. Fulfillment Through Ishmael’s Lineage: They believe that the widespread influence and significance of Ishmael’s descendants fulfill the covenantal promises more broadly and inclusively, aligning with the idea of being a blessing to all nations.

In summary, the viewpoint that the Abrahamic covenant is realized through Ishmael instead of Isaac is based on scriptural interpretations, historical context, and theological perspectives. This stands in contrast to the conventional interpretation of the covenant, which is linked to Isaac’s descendants, and underscores notable distinctions between the Abrahamic and Sinai covenants.

Islam: Restoration of Abrahamic Faith - Theological Perspectives and Historical Claims

Islam is often regarded as a restored religion of Abraham, a belief held by its followers who argue that both Judaism and Christianity have deviated from the original teachings that Abraham imparted. This perspective is rooted in the Islamic understanding of religious history and the role of prophets, which includes a staunch belief in the oneness of God (Tawhid) and a commitment to following the path laid down by earlier prophets.

Adherents of Islam assert that Judaism has altered the narrative surrounding the sacrifice of Abraham's son. In the Islamic tradition, it is believed that the son intended for sacrifice was Ishmael, rather than Isaac. This belief is significant in Islamic theology as it emphasizes Ishmael's importance in the lineage of prophets, particularly because he is considered an ancestor of the Prophet Muhammad. This interpretation contrasts with the Jewish tradition, which identifies Isaac as the significant figure in this narrative. The Islamic stance highlights the idea that the earlier teachings regarding the significance of sacrifice and obedience to God have been misrepresented or transformed over time within the Jewish faith.

Moreover, Islam critiques Christianity for departing from strict monotheism by introducing the doctrine of the Trinity, which represents God as three distinct persons in one essence: the Father, the Son, and the Holy Spirit. From the Islamic perspective, this concept compromises the fundamental belief in the absolute oneness of God, which is a core tenet of Islam. Furthermore, followers of Islam believe that Christianity has altered certain religious practices, including the practice of circumcision, which is seen in the Jewish tradition as a covenantal sign between God and Abraham's descendants. Muslims maintain that these modifications reflect a broader deviation from the original teachings provided to Abraham and the subsequent prophets.

In essence, from the Islamic viewpoint, Islam is viewed as the true restoration of the teachings of Abraham and the final message of God. This belief is prominently articulated in the Quran, which Muslims regard as the literal word of God as revealed to Muhammad. The Quran not only upholds the messages and doctrines of previous prophets but also clarifies perceived distortions in their teachings, reaffirming the importance of monotheism and a direct relationship with God without intermediaries. Thus, Islamic theology sees itself as the culmination and fulfillment of the divine guidance that began with Abraham, aiming to correct and restore the spiritual path for humanity as intended by the Creator.

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.
