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]:
The account naming Isaac comes down to us through Abu Kurayb - Zayd b. al-Hubab - al-Hasan b. Dinar - 'Ali b. Zayd b. Jud'an - al-Hasan - al-Ahnaf b. Qays - al-'Abbas b. 'Abd al-Muttalib - THE PROPHET in a conversation in which he said, "Then we ransomed him with a tremendous victim." And he also said, "HE IS ISAAC."
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.
Finally, Tabari himself:
"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).
In another volume, al-Tabari states:
... That ram remained in custody with God until He let it go AS ISAAC'S RANSOM ... (The History of Al-Tabari: General Introduction and From the Creation to the Flood, translated by Franz Rosenthal [State University of New York Press (SUNY), Albany, 1989], Volume 1, p. 310; capital emphasis ours)
In Musnad Ahmad, Number 2658, we are told:
The messenger of God said that Gabriel took Abraham to Jamra al-Aqabah (the upper Jamrah, the pillar or place for stoning) and then Satan appeared to him. Then he stoned Satan with seven stones so he fainted him to faint. Then he came to the middle Jamrah, and Satan again appeared to him. He again stoned him with seven stones causing Satan to faint. He then came to the lower Jamrah, and Satan again appeared to him. Again he stoned Satan, causing him to faint once again. Now when Abraham wanted to slaughter his son Isaac, he said his father, "Father, tie me so I don’t get afraid and my blood splash all over you when you slaughter me." So he took him and he tied him up, and then he took the knife. And when he wanted to slay him a voice called from behind him, "O Abraham, the vision has been fulfilled."
