Question: I keep hearing that the Bible references Islam before it split from Judaism in the Old Testament. Is that for real, and, where can I find it? It seems like there’s a chance to heal that breach, and the answer is in the Bible somewhere. Just like witnessing to Jews, only more difficult.
Answer: Islam did not start until roughly 600 A.D. You’re probably thinking about how Ishmael and Isaac were separated in a sense as they each fathered separate nations. Ishmael was removed from Abraham’s family when Isaac was identified as the child of promise from God to Abraham and Sarah. Muslims argue that Ishmael was the favored child and meant for the greater destiny, i.e., Islam. In fact, they teach that it was Ishmael and not Isaac who was offered as a sacrifice before God provided a substitute animal. But check out Genesis 21 and 22.
