Satan chose the children of Ishmael for one of his masterpiece counterfeit religions because Ishmael's descendants have been jealous and have coveted God's covenant relationship with the Jews, the children of Isaac and Jacob, since the beginning of that everlasting covenant.
Sadly, because their hearts were filled with envy, rather than accepting the many blessings God has bestowed on them as well, the children of Ishmael were an easy target for deceiving spirits — hence their following the path of the false moon god allah to this day, claiming he is the same as YHWH. He is not the same, and God will not be mocked!
