I have copied and pasted the following from Sam's Deceptive Article:

ANY ONE READING ALL THE ABOVE VERSES CAN TELL YOU THAT THE COMMAND FROM ALLAH FOR THE SACRIFICE CAME BEFORE ISAAC WAS BORN AND WHEN ISHMAEL WAS OF SERIOUS WORKING AGE.

"The earliest sages of our Prophet's nation disagree about which of Abraham's two sons it was that he was commanded to sacrifice. Some say it was Isaac, while others say it was Ishmael. Both views are supported by statements related on the authority of the Messenger of God. If both groups of statements were equally sound, then - since they both came from the Prophet - only the Quran could serve as proof that the account naming Isaac is clearly the more truthful of the two." (2: p. 32).

Instead of listing both sides of the argument, our paper will therefore focus on those who said it was Isaac. All the following quotations are found in al-Tabari (2: pp. 82-86) [italics our emphasis]:

'According to Abu Kurayb - Ibn Yaman-Mubarak - al-Hasan-al-Ahnaf b. Qays-al - 'Abbas b. 'Abd al-Muttalib: The quote, "Then We ransomed him with a tremendous victim," refers to Isaac.

According to al-Husayn b. Yazid al-Tahhan - Ibn Idris - Dawud b. Abi Hind - 'Ikrimah - Ibn 'Abbas: The one whom Abraham was ordered to sacrifice was Isaac.

According to Ya'qub - Ibn 'Ulayyah - Dawud - 'Ikrimah - Ibn 'Abbas: The victim was Isaac.

According to Ibn al-Muthanna - Muhammad b. Ja'far - Shu'bah - Abu Ishaq - Abu al-Ahwas: A certain man boasted to Ibn Mas'ud, "I am so-and-so son of so-and-so, son of the noble elders." And 'Abdallah said,"This is Joseph b. Jacob, son of Isaac the victim of God, son of Abraham the Friend of God."

According Ibn Humayd - Ibrahi, b. al-Mukhtar - Muhammad b. Ishaq - 'Abd al-Rahman b. Abi Bakr - al-Zyhri - al-'Ala' b. Jariyah al-Thaqafi - Abu Hurayrah - Ka'b: When God said, "Then We ransomed him with a tremendous victim," He was speaking of Abraham's son Isaac.

According to Ibn Humayd - Salamah - Muhammad b. Ishaq- 'Abdallah b. Abi Bakr - Muhammad b. Muslim al-Zuri - Abu Sufyan b. al-'Ala' b. Jariyah al-Thaqafi, the confederate of Banu Zuhrah - Abu Hurayrah - Ka'b al-Ahbar: The son whom Abraham was commanded to sacrifice was Isaac.

According to Yunus - Ibn Wahb - Yunus - Ibn Shihab - 'Amr b. Abi Sufyan b. Usayd b. Jariyah al-Thaqafi: Ka'b said to Abu Hurayrah, "Should I tell you about Isaac, the son of the prophet Abraham? Abu Hurayrah said, "Certainly." So Ka'b gave the following account:

"When Abraham was told to sacrifice Isaac, Satan said `By God! If I cannot deceive the people of Abraham with this, I shall never be able to do it.' So when Abraham went out with Isaac to sacrifice him, Satan visited Abraham's wife, Sarah, in the shape of a man whom Abraham's people knew, and asked her, `Where is Abraham going so early with Isaac?' She said, `He went off early on some errand.' Satan said, `No, by God! That is not the reason he left so early.' Sarah asked, `Then what is the reason?' He said, `He took him out early to sacrifice him.' Sarah said, `There is no truth to that, he would not ... sacrifice his own son.' Satan said, `By God it is true.' Sarah said, `And why would he sacrifice him?' He replied, `He claims that his Lord ordered him to do it.' Sarah said, `If his Lord ordered him to do that, it is best that he obey.' Then Satan left Sarah and went to Isaac, who was walking with his father, and said, `Where is your father taking you so early?' Isaac answered, `He is taking me on some errand of his.' Satan said, `No, by God, he is not taking you out on an errand. He is taking you out early to sacrifice you.' Isaac said, `My father would not sacrifice me.' Satan told him, `Certainly he would.' Isaac asked, `Why?' Satan told him, `He claims that his Lord ordered him to do it.' Isaac answered, `By God! If the Lord told my father to do that, he should certainly obey him.' So Satan left him and went on to Abraham, saying, `Why are you taking your son out early?' Abraham said, `I am taking him on an errand.' Satan answered, `By God, you took him out early only to sacrifice him.' Abraham asked, `Why would I do that?' Satan said, `You claim that your Lord ordered you to do it.' Abraham said, `By God, if my Lord orders me to do that, I will surely do it.' When Abraham took Isaac to sacrifice him, God stayed his hand and ransomed him with a `tremendous victim.' Abraham said to Isaac, `Arise, my little son, for God has released you.' And God said to Isaac, `I will grant you any prayer you choose to make now.' Isaac said, `My God! I pray to you that I be granted this, that you grant entry into Paradise to any worshipper, past or present, who encounters you and does not make anything a partner with you'."

According to 'Amr b. Ali - Abu 'Asim - Sufyan - Zayd b. Aslam - 'Abdallah b. 'Ubayd b. 'Umayr - his father: Moses said, "O Lord! Why are you addressed as `O God of Abraham, Isaac, and Jacob?'" God answered, "Abraham never considered anything at all equal to Me, but put Me above all things; Isaac was generous to Me in the matter of the sacrifice and in other matters; and as for Jacob, the more tribulations I inflicted upon him the more good thoughts he thought about me."

According to Ibn Bashshar - Mu'ammal - Sufyan - Zayd b. Aslam - 'Abdallah b. 'Ubayd b. 'Umayr - his father: Moses asked God, "O Lord! Why did you give Abraham, Isaac, and Jacob what you gave them?" And God's answer was the same (as that given above).

According to Abu Kurayb - Ibn Yaman - Isra'il - Jabir - Ibn Sabit: He was Isaac.

According to Kurayb - Ibn Yaman - Sufyan - Abu Sinan al-Shaybani - Ibn Abi al-Hudhayl: The victim was Isaac.

According to Abu Kurayb - Sufyan b. 'Uqbah - Hmaza al-Zayyat - Abu Ishaq - Abu Maysarah: Joseph told the king to his face, "You wish to eat with me when I, by God, am Joseph son of Jacob the prophet of God, son of Isaac the victim of God, son of Abraham the friend of God."

According to Abu Kurayb - Waki' - Sufyan - Abu Sinan - Ibn Abi al-Hudhayl: Joseph said to the king... The same (rest of the) account is roughly the same.

According to Musa b. Harun - 'Amr b. Hammad - Asbat - al-Suddi - Abu Malik and Abu Salih - Ibn 'Abbas and Murrah al-Hamdani - Ibn Mas'ud and some of the companions of the Prophet: Abraham was instructed in a dream to "carry out your promise that if God granted you a son by Sarah you would sacrifice him."

According to Ya'qub - Husahym - Zakariya' and Shu'bah - Abu Ishaq - Masruq: When God said, "The We ransomed him with a tremendous victim," that was Isaac.

"As for the above-mentioned proof from the Quran that it really was Isaac, it is God's word which informs us about the prayer of His friend Abraham when he left his people to migrate to Syria with Sarah. Abraham prayed, `I am going to my Lord who will guide me. My Lord! Grant me a righteous child.' This was before he knew Hagar, who was to be the mother of Ishmael. After mentioning this prayer, God goes on to describe the prayer and mentions that he foretold to Abraham that he would have a gentle son. God also mentions Abraham's vision of himself sacrificing that son when he was old enough to walk with him. The Book does not mention any tidings of a male child given to Abraham except in the instance where it refers to Isaac, in which God said, `And his wife, standing by laughed when we gave her tidings of Isaac, and after Isaac, Jacob', and `Then he became fearful of them'. They said. `Fear not!' and gave him tidings of a wise son. Then his wife approached, moaning, and smote her face, and cried, `A barren old woman'. Thus, wherever the Quran mentions God giving tidings of the birth of a son to Abraham, it refers to Sarah (and thus to Isaac) and the same must be true of God's words `So we gave him tidings of a gentle son', as it is true of all such references in the Quran." (Ibid. p. 89).

"Akrama asked: `Who was supposed to have been slain?'

Abdallah answered: `Ishmael!'

'Why?' asked Akrama.

Ben Abbas answered: `Because how can God pass the good news of Isaac's birth to Abraham, then order that he be killed?'

`I can bring you proof from the Koran that Isaac was supposed to have been slain'. Said Akrama, `Thus will thy Lord prefer thee and teach thee the interpretation of events, and perfect His grace upon thee and upon the household of Jacob as He perfected it upon thy fathers, Abraham and Isaac. Lo! Thy Lord is All-Knowing and All-Wise'. (Joseph 6).

`God's blessing to Abraham was by choosing him, and saving him', said Akrama, `and to Isaac by redeeming him from slaying'." (3: pp. 52-53).

Also,

As the Kur'an verse above quoted does not state which son was to have been sacrificed, many Muslim theologians refer the intended sacrifice to Isma`il ... But it may be said that the oldest tradition - al-Tha`labi expressly emphasises the ashab and tabi`un, i.e. the Companions of the Prophet and their successors from `Umar b. al-Khattab to Ka`b al-Ahbar - did not differ from the Bible on this question. (Gibb and Kramers, A Shorter Encyclopaedia of Islam, p. 175).

The differing views held amongst the Muslims as to the identity of the child only proves that the Bible is truly authoritative and reliable since what the Quran does not clarify, the Bible corrects and addresses, leaving no guesswork for scholars to work through."

"Firstly we read that the son to be sacrificed was promised to Abraham: Fabash-sharnaahu bighulaamin haliim - We announced to him an upright boy (Surah 37.101); and we read further that Isaac was specifically promised to him by name: Fabash-sharnuahu bi-Ishaaq - We announced to him Isaac (Surah 37.112). Nowhere in the Qur'an is it ever similarly stated that Ishmael was promised to Abraham.

"Secondly there is a clear symmetry between these words: Falammaa aslamaa - when they had both submitted (Surah 37.103), and Wa baaraknaa alayhi wa alaa Ishaaq - And we blessed him and Isaac (Surah 37.113). As Abraham and Isaac had both fully submitted themselves to God's will that the one should sacrifice the other, it was only reasonable that God's blessing should come upon them both.

"It is significant that there is no word in the text, such as thumma ("then"), between the story of the sacrifice and the mention of Isaac to distinguish the two or give them a different time period. The Muslim argument that Ishmael must have been the sacrificial son because the story of the sacrifice precedes the mention of Isaac is shown to be highly vulnerable upon closer analysis. Certainly the complete omission of Ishmael's name in the passage considerably undermines the dogmatic contemporary Muslim claim that he was the son who was commanded to be sacrificed."

It is strange that the name of Hagar should not be mentioned in the Qur'an. (Stanton, The Teaching of the Qur'an, p. 46).

"In actual fact, the Qur'an has no reference to her whatsoever, let alone by name. In this section we shall shortly see that the Qur'an speaks plainly of Isaac's mother as the wife of Abraham, the only wife of the prophet to whom there is any reference. Is not the complete silence in the Qur'an about Hagar, the mother if Ishmael, a testimony to the fact that Sarah alone was the wife of Abraham and that Hagar was merely her mistress? The Muslim argument that Ishmael was the sacrificial son quite clearly has no solid evidence to substantiate it. The plain statements in the Bible that it was Isaac must obviously be preferred to the Qur'an's nebulous and at times confusing treatment of the identity of the son whom Abraham was commanded to sacrifice."

"When the promise of Isaac came to Abraham and Sarah, Ishmael had already been born, and the mention of Sarah at this point as Abraham's only wife is a clear testimony that Hagar was not one of his wives. We also note once again that there is no mention of Hagar in the Qur'an whatsoever, a strange omission if she also was a wife of Abraham. In fact no one reading through the Qur'an without reference to any other work could possibly guess that there was another woman in Abraham's life. The only such woman mentioned is described as the single wife of Abraham and she is expressly described as the mother of Isaac. If, therefore, Sarah is mentioned in the Qur'an alone as the wife of Abraham and is also so described in the Bible, can there be any further objection to the description of Isaac as "your only son" in Genesis 22.2 when the command comes to Abraham to sacrifice him? If Sarah is the only legitimate wife of Abraham, is it not perfectly in order to describe her son Isaac as Abraham's only son as well?

"This matter begs further scrutiny. We must bear in mind that a promise was made to Abraham that he would bear a son through his wife. In the Bible the promise comes directly by the Word of God to Abraham (Genesis 17.19), whereas in the Qur'an it comes through the heavenly messengers who have come to destroy the people of Lot (Surah 11.70). In both cases, however, it is the express promise of God that a son would be born to Abraham and that the son would be Isaac. In Surah 15. 53 the narrative is repeated and the promise of a son again appears, though this time Isaac is not mentioned by name. The same goes for Surah 51.28-29 where once again the promise of a son to Abraham's only wife (again imra 'ah in the singular) is repeated. Once again Yusuf Ali, in a footnote, takes it to be Sarah (The Holy Qur'an, p. 1424). Finally, as we have seen, the promise of a son to Abraham appears again at the introduction of the story of the sacrifice (Surah 37.101) and a little lower down the promised son is again specifically named Isaac (Surah 37.112). There can be no doubt that Isaac is the only son promised to Abraham in the Qur'an and he must therefore be identified as the intended sacrificial son.

Ishmael is nowhere mentioned as the child of promise. (Wherry, A Comprehensive Commentary on the Qur'an, Vol. 2, p. 360).

"As Sarah alone is mentioned in the Qur'an and as the single wife of Abraham, it is surely too hard to believe that God would announce to him the birth of a ghulamin halimin, a righteous boy (Surah 37.101), by an illegitimate union with a slave woman, especially as no mention whatsoever of this woman appears in the Qur'an. The only son promised to Abraham in the Qur'an is Isaac and, as Surah 37.102 makes it quite plain that it was this very same promised son who was to be sacrificed, the only reasonable conclusion we can draw is that the Qur'an takes no issue with the Bible on the specific identification of the sacrificial son as Isaac. It is only the popular sentiment of the Muslims that it was Ishmael and that for obvious reasons. We have shown just how the promise of a son to Abraham was inextricably linked to the subsequent command to sacrifice him and how Abraham, through a deliberate consideration of all that was involved against the background of God's unchanging faithfulness, foresaw the coming of the Son of God into the world together with his sacrificial death and subsequent resurrection."

The Bible repeatedly records that the Command from God to prophet Abraham (p.b.u.h.) was to Sacrifice "thy only son". This particular phrase "thy only son" could only be used when Abraham had ONLY ONE SON.

Hence, due to the great time factor involved it is not hard to see how stories of Muhammad's miracles could be forged and circulated, seeing that no eyewitnesses were present who could prevent any myths from taking place."
