# Isaac and Ishmael: Who Received the Covenant? > God blessed Ishmael and promised him a great nation. Genesis gives the covenant, and the son of the offering, to Isaac. - Canonical: https://apologetics.wiki/islam/isaac-and-ishmael - Religions: Islam - Denominations: none - Beliefs: none - Tags: isaac, ishmael, covenant, abraham - Updated: 2026-11-07 - Author: [Paul Ambrose](https://apologetics.wiki/author/hi-its-paul) God blessed Ishmael and said he would be a great nation. The covenant God names with Abraham, and the son Abraham is told to offer, are Isaac’s. [Genesis 17:21](/bible/genesis/17/21) says, “But my covenant will I establish with Isaac.” [Genesis 22:2](/bible/genesis/22/2) calls that son “thine only son Isaac.” ## Key Points - [Genesis 16:11](/bible/genesis/16/11) names Ishmael before he is born. [Genesis 17:20](/bible/genesis/17/20) blesses him, promises twelve princes, and says God will make him a great nation. - [Genesis 17:19](/bible/genesis/17/19) and [17:21](/bible/genesis/17/21) put the everlasting covenant with Isaac, the son Sarah will bear. [Genesis 21:12](/bible/genesis/21/12) says, “in Isaac shall thy seed be called.” - [Genesis 22:2](/bible/genesis/22/2) tells Abraham to offer “thy son, thine only son Isaac.” The verse prints the name. - [Galatians 4:28](/bible/galatians/4) says believers, “as Isaac was, are the children of promise.” [Galatians 4:30](/bible/galatians/4) says the son of the bondwoman shall not be heir with the son of the freewoman. - [Qur’an 37:100–111](https://quran.com/as-saffat/100-113?translations=20), Saheeh International, tells of a forbearing boy and a dream of sacrifice, and does not name the boy. [Qur’an 37:112](https://quran.com/as-saffat/112?translations=20) then gives “good tidings of Isaac.” - [Ibn Kathir on 37:102](https://quran.com/as-saffat/102/tafsirs/en-tafisr-ibn-kathir) says the boy was Ishmael, the first son, and that the People of the Book inserted Isaac into their scripture. ## What God Said About Each Son Ishmael is Abraham’s son by Hagar. The angel tells Hagar, in [Genesis 16:11–12](/bible/genesis/16), that she will bear Ishmael and that he shall dwell in the presence of all his brethren. Abraham asks, in [Genesis 17:18](/bible/genesis/17), “O that Ishmael might live before thee!” The answer is not a refusal of Ishmael. [Genesis 17:20](/bible/genesis/17/20): “Behold, I have blessed him, and will make him fruitful, and will multiply him exceedingly; twelve princes shall he beget, and I will make him a great nation.” The next sentence draws the line. [Genesis 17:21](/bible/genesis/17/21): “But my covenant will I establish with Isaac, which Sarah shall bear unto thee at this set time in the next year.” [Genesis 21:12](/bible/genesis/21/12) says the same thing when Hagar and the boy are sent out: “in Isaac shall thy seed be called.” A blessing and a nation are stated for Ishmael. The covenant sentence, and the line called Abraham’s seed, are stated for Isaac. [Genesis 25:12–16](/bible/genesis/25) lists Ishmael’s twelve sons. The list is a fulfillment of the promise of princes. It is not the covenant paragraph of chapter 17. ## The Son on the Mountain [Genesis 22:2](/bible/genesis/22/2), King James Version: > And he said, Take now thy son, thine only son Isaac, whom thou lovest, and get thee into the land of Moriah; and offer him there for a burnt offering upon one of the mountains which I will tell thee of. The verse names Isaac. “Only son,” in this sentence, is said while Ishmael is already born. The narrative’s own word for the son of the offering is Isaac, not a blank that a later reader fills. [Genesis 22:16–18](/bible/genesis/22) swears the blessing to Abraham’s seed after that test, the seed in whom all nations will be blessed. [Galatians 3:16](/bible/galatians/3) says that seed is Christ. The Christian claim is not that Ishmael was unblessed. It is that the oath and the offering in Genesis are Isaac’s, and that the New Testament reads that line as leading to Jesus. [Galatians 4:22–30](/bible/galatians/4) retells the two sons as an allegory: the son of the bondwoman and the son of the freewoman. “Now we, brethren, as Isaac was, are the children of promise.” The citation of Genesis is explicit: cast out the bondwoman and her son, “for the son of the bondwoman shall not be heir with the son of the freewoman.” Paul is arguing about law and promise in the churches of Galatia, not drawing a map of modern nations. The heir, in his sentence, is the child of promise, identified with Isaac. ## What the Qur’an and Ibn Kathir Say [Qur’an 37:100–113](https://quran.com/as-saffat/100-113?translations=20) is the passage Muslims bring to this question. Saheeh International: > [100] My Lord, grant me [a child] from among the righteous. [101] So We gave him good tidings of a forbearing boy. [102] And when he reached with him [the age of] exertion, he said, “O my son, indeed I have seen in a dream that I [must] sacrifice you, so see what you think.” He said, “O my father, do as you are commanded. You will find me, if Allāh wills, of the steadfast.” The boy is not named in those verses. The dream is a sacrifice. The son consents. [Qur’an 37:103–107](https://quran.com/as-saffat/103?translations=20) says they both submitted, the father put him down on his forehead, and “We ransomed him with a great sacrifice.” Then [Qur’an 37:112](https://quran.com/as-saffat/112?translations=20): “And We gave him good tidings of Isaac, a prophet from among the righteous.” [Qur’an 37:113](https://quran.com/as-saffat/113?translations=20) blesses him and Isaac. A reader who has only the Arabic order, in this English, meets an unnamed boy, a ransom, and then a separate glad tiding of Isaac. [Ibn Kathir on 37:102](https://quran.com/as-saffat/102/tafsirs/en-tafisr-ibn-kathir) names the boy. “This child was Isma‘il, peace be upon him, for he was the first child of whom glad tidings were given to Ibrahim, peace be upon him, and he was older than Ishaq.” He says Muslims and the People of the Book agree that Ishmael was born when Abraham was eighty-six and Isaac when Abraham was ninety-nine, and that “according to their Book, Allah commanded Ibrahim to sacrifice his only son,” but “here they falsely inserted the name of Ishaq.” He says they did so because Isaac is their ancestor and Ishmael is the ancestor of the Arabs. He quotes Ibn Abbas: “The one who was ransomed was Isma‘il… The Jews claimed that it was Ishaq, but the Jews lied.” He also records Muhammad ibn Ka‘b’s argument from the Qur’an itself: after the sacrifice story, God gives glad tidings of Isaac, and [Qur’an 11:71](https://quran.com/hud/71) gives glad tidings of Isaac and then of Jacob, so the son who was to be sacrificed could not be the son who was already promised a son. That is the Muslim case at full strength, in a commentary Muslims read. The concession is on the page of the Qur’an itself: 37:100–111 does not print Ishmael’s name. The name enters in the tafsir, and in the claim that Genesis inserted Isaac. Genesis 22:2, as published here, already contains the name. A charge of insertion has to show a text of Genesis 22 that lacked it. This page does not have such a text. [Was the Bible Corrupted?](/islam/was-the-bible-corrupted) is that wider claim. Christians do not deny Ishmael’s blessing or the twelve princes. They deny that the covenant sentence moved. [Genesis 17:20](/bible/genesis/17/20) and [17:21](/bible/genesis/17/21) stand next to each other: a great nation, and “but my covenant… with Isaac.” The son of the offering, in Genesis 22, is named Isaac. The New Testament identifies Jesus as the seed and as the Son, and it identifies believers as children of promise like Isaac. Jesus is God. That further claim is [the deity of Christ](/christianity/deity-of-christ), not a denial that Ishmael was Abraham’s son. ## Frequently Asked Questions ### Was Ishmael Abraham’s Son? Yes. [Genesis 16:15](/bible/genesis/16) says Hagar bore Abram a son and Abram called him Ishmael. [Genesis 17:20](/bible/genesis/17/20) blesses him. ### How Old Was Abraham When Isaac Was Born? [Genesis 17:17](/bible/genesis/17) has Abraham set his age at a hundred when he hears Sarah will bear a son. [Genesis 21:5](/bible/genesis/21/5) says he was a hundred years old when Isaac was born. The cited English translation of Ibn Kathir says Ishmael was born when Abraham was eighty-six and Isaac when he was ninety-nine; Genesis 21:5 instead gives one hundred for Isaac’s birth. ### Which Son Did Abraham Offer? [Genesis 22:2](/bible/genesis/22/2) says Isaac. [Qur’an 37:102](https://quran.com/as-saffat/102?translations=20) does not name the son. Ibn Kathir says Ishmael. ## Keep Reading - [What Do Muslims Believe?](/islam/what-do-muslims-believe) - [Is Muhammad the Prophet of Deuteronomy 18?](/islam/is-muhammad-the-prophet-of-deuteronomy-18) - [Does Isaiah Prophesy Muhammad?](/islam/does-isaiah-prophesy-muhammad) - [Was the Bible Corrupted?](/islam/was-the-bible-corrupted) - [The Trinity](/christianity/the-trinity) - [Did Jesus Ever Claim to Be God?](/christianity/deity-of-christ) - [What Does the Bible Say About Salvation?](/christianity/what-does-the-bible-say-about-salvation) ## Passages Quoted on This Page ### Genesis 16:11 King James Version. > And the angel of the LORD said unto her, Behold, thou art with child, and shalt bear a son, and shalt call his name Ishmael; because the LORD hath heard thy affliction. ### Genesis 17:20 King James Version. > And as for Ishmael, I have heard thee: Behold, I have blessed him, and will make him fruitful, and will multiply him exceedingly; twelve princes shall he beget, and I will make him a great nation. ### Genesis 17:19 King James Version. > And God said, Sarah thy wife shall bear thee a son indeed; and thou shalt call his name Isaac: and I will establish my covenant with him for an everlasting covenant, and with his seed after him. ### Genesis 21:12 King James Version. > And God said unto Abraham, Let it not be grievous in thy sight because of the lad, and because of thy bondwoman; in all that Sarah hath said unto thee, hearken unto her voice; for in Isaac shall thy seed be called. ### Galatians 4:30 King James Version. > Nevertheless what saith the scripture?

[4:23] But he who was of the bondwoman was born after the flesh; but he of the freewoman was by promise. [4:24] Which things are an allegory: for these are the two covenants; the one from the mount Sinai, which gendereth to bondage, which is Agar. [4:25] For this Agar is mount Sinai in Arabia, and answereth to Jerusalem which now is, and is in bondage with her children. [4:26] But Jerusalem which is above is free, which is the mother of us all. [4:27] For it is written, Rejoice, thou barren that bearest not; break forth and cry, thou that travailest not: for the desolate hath many more children than she which hath an husband. [4:28] Now we, brethren, as Isaac was, are the children of promise. [4:29] But as then he that was born after the flesh persecuted him that was born after the Spirit, even so it is now. [4:30] Nevertheless what saith the scripture? Cast out the bondwoman and her son: for the son of the bondwoman shall not be heir with the son of the freewoman. ### Qur’an 37:113 Saheeh International.
