Actually, the Koran tries to put the Muslims at the center of the Biblical stories. For example, in the Koran, the son whom Abraham was told to sacrifice was Ishmael, not Isaac. Their biggest annual celebration, Eid, commemorates the saving of Ishmael from sacrifice.
In other words, it’s all made-up rubbish, “islam” being an ideology, a political system, thinly veiled as “religion.” Let the buyer beware.
