Isaac (Ishaq) and the Biblical Covenant Line
Isaac, known in the Qur’an as Ishaq, stands in Abrahamic sacred history as son of Abraham and Sarah, child of promise, prophet, righteous servant, and bearer of the biblical covenant line that continues through Jacob, Israel, Moses, David, Mary, Jesus, and the prophetic memory of the Children of Israel. In Genesis, Isaac receives the covenantal promise associated with Abraham’s descendants, land, blessing, and the formation of Israel’s sacred history. In the Qur’an, Ishaq is honored as a prophet and righteous one, but his line is not used to erase Ishmael. Through a Qur’an-centered comparative lens, this article reads Isaac as a true Abrahamic heir whose covenantal meaning is strongest when placed beside, not against, the Ishmaelite line.
