It is often noted that Mohammed is a descendent of Abraham and follows the same faith as Abraham. Every generation from Adam through Abraham had a relationship with the One True God. Every subsequent generation from Abraham’s son Isaac also has a relationship with the One True God. The linage of Jesus only includes those with a relationship with the One True God going all the way back to Adam.
Until Mohammed the descendents of Ishmael seemed to fall from monotheism and became polytheist. Every prophet of God was a descendent of only monotheist, yet Mohammed claims to be the last and greatest prophet of God while his linage includes twenty-three (assuming Ishmael retained the faith of his father) generations of pagans. The linage of Mohammed includes more polytheist than monotheist. This is terribly inconsistent with the linage of every prophet of God and I am curious as to how Muslims explain this inconsistency aside from simply stating it is the will of God.
