Muslims believe that Ishmael was the child Abraham was commanded to sacrifice, as he was Abraham's only son for over 13 years.

The Bible explicitly states that Isaac is Abraham's only son whom he was commanded to sacrifice, as seen in Genesis 22:1-2. This is further supported by New Testament references in Hebrews 11:17 and James 2:21, which affirm Isaac's unique status as the child of promise. In contrast, while Muslims argue that Ishmael was the only son for a period, they overlook that Isaac was the only promised child, conceived miraculously, and destined for the inheritance of God's covenant. The Quran acknowledges Isaac's unique status as the promised child, aligning with the biblical narrative. Additionally, the Quran does not name the child of sacrifice, which raises questions about the certainty of the Islamic claim regarding Ishmael.
