And We did certainly give the Children of Israel the Scripture and judgement and prophethood, and We provided them with good things and preferred them over the worlds.
Qur'an 45:16
And We gave to Him Isaac and Jacob and placed in his descendants prophethood and scripture. And We gave him his reward in this world, and indeed, he is in the Hereafter among the righteous.
Qur'an 29:27
Jacob is also known as Israel. He was the son of Isaac.
The Qur'an says loud and clear that prophets as scripture come from this lineage. But Mohammed made up a lineage for himself going back to Ishmael. Ishamel would have been Jacob's half-uncle, and obviously NOT in the line of Isaac-Jacob.
So by his own confused Qur'an Mohammed actually admitted that the was no prophet, and basically a fraud.
So he messed up his own cover story. Again.
