Well, if you look at it from an Islamic standpoint, Islam would definitely exist and trump both Judaism and Zoroastrianism and take the place of Christianity ATL.

Of course, that's from the Muslim's eyes.

By the Jew, Islam would rise as a spinoff from a small branch of Judaism.

By the Christian, Islam would rise and fall swiftly.

Also, Pita, Muslims believe that Abraham was going to sacrifice Ishmael, but at the last moment, but then God delivered a ram for him to slaughter. (Muslim standpoint.)
