Why do Muslims say it was ishmail and not isaac that was to be sacrificed?

Muslims believe it was Ishmael, not Isaac, who was to be sacrificed based on interpretations of the Quran, particularly Surah As-Saffat (37:102-107). Islamic tradition holds that Ishmael was the son whom Abraham (Ibrahim) was commanded to sacrifice as a test of faith. This belief emphasizes Ishmael's significance in Islamic heritage and his role as an ancestor of the Prophet Muhammad. The distinction reflects broader theological differences between Islam and Judaism/Christianity regarding the lineage and prophetic roles of the two sons.
