Yes they do come from Ishmael, but the fact remains they all interpret Abraham's teachings differently.1.Because, compared to pre-Islamic Arab paganism, Judeo-Christianity was the only monotheistic faith at the time of Muhammad.
2.Islam traces it's spiritual heritage back to Ishmael, not Isaac:
Galatians 4:
28 Now you, brothers and sisters, like Isaac, are children of promise. 29 At that time the son born according to the flesh persecuted the son born by the power of the Spirit. It is the same now. 30 But what does Scripture say? “Get rid of the slave woman and her son, for the slave woman’s son will never share in the inheritance with the free woman’s son.” 31 Therefore, brothers and sisters, we are not children of the slave woman, but of the free woman.
