The debate centered first on the identity and status of the Injil. Muslim participants generally described it as revelation or scripture given to Jesus, sometimes saying it was later written down and corrupted, while the Christian side pressed for a concrete account of what text the Quran means when it says Muhammad is found written in the Torah and Gospel. Quran 7:157 was a recurring anchor for the Christian challenge, paired with Quran 5:47 and 5:43 to argue that the Quran treats the Torah and Gospel as available and authoritative. Muslim replies appealed to verses such as Quran 19:30, 57:27, 2:79, and 61:6 to frame the Injil as revelation to Jesus, corrupted in transmission, and fulfilled by Quranic testimony about Ahmad. The exchange repeatedly returned to whether “whatever agrees with the Quran” can identify the true Injil, with the Christian side testing that criterion through examples such as the Gospel of Thomas.

A second major arc concerned continuity, contradiction, and preservation. The Christian side argued that later claimants must not contradict prior revelation, citing Deuteronomy 13 and 18, and applied this to Muhammad’s relationship to the Gospel, especially on Jesus’ crucifixion and exclusive role in salvation through Galatians 1:8-9, Quran 4:157, and John 14:6. Muslim participants challenged the principle by pointing to biblical covenantal developments or changes in divine dealings, including Genesis flood texts and questions about Jesus fulfilling Mosaic law in Matthew 5:17. The Christian response appealed to New Covenant prophecy, especially Jeremiah 31:31, to distinguish foretold covenantal development from contradiction. Preservation claims also became a recurring issue: Quran 15:9, 21:48, and 6:115 were debated over whether Allah’s protection of “the reminder” and the unchangeability of Allah’s words apply only to the Quran or also to earlier scriptures.

Later discussion widened into Islamic doctrine and moral criticism. The Christian side used hadith and Quranic passages such as Sahih Muslim 2643a, Sahih Muslim 2662c, Quran 76:29-31, and Quran 10:99-100 to argue that Islamic sources undermine human free will by making belief, deeds, and final destiny dependent on Allah’s prior will. It also cited reports and verses connected to Muhammad’s marriage to Zaynab, the abolition of adoptive sonship, relations with a female slave, wife-beating, and captives in war, including Quran 33:37, 33:4, 66:1, 4:34, 4:24, and Sunan an-Nasa’i 3959, as part of a broader challenge to Muhammad’s prophethood and moral example. The debate also briefly addressed Christian prayer and identity, using 2 Corinthians 13:14 for Trinitarian prayer language and 1 Corinthians 15:3-4 to define Christian faith as confession of Christ’s death and resurrection rather than birth identity.

Reference patterns show heavy use of Quranic texts by both sides, with the Christian side often citing the Quran to create internal critiques of Islamic claims about the Bible, preservation, prophecy, and free will. Biblical references were used mainly to defend the canonical Gospels, covenantal continuity, apostolic reliability, and tests of prophethood, while hadith citations appeared mostly in later sections on predestination, Muhammad’s conduct, and Quranic preservation variants. The transcript windows are bounded and truncated, so this summary reflects the curated argument spine and visible flow rather than a complete account of every exchange.
