Ishmael did not start Islam. Islam was founded by the Prophet Muhammad in the 7th century AD.
NO! There is no documented proof that Mohammad is connected to Ishmael. There is over 2000 years of Mohammad's lineage that cannot be accounted for, for him to be a descendant of Ishmael.
No. The Muslim perspective is that Islam started with Adam, the first man, because Islam is the natural state of a person until he is corrupted by other religions/beliefs/atheism. The Historical perspective is that the first Muslim was Mohammed since it is the Qur'an which forms the basis for Muslim religious practice. Since Adam comes before Ishmael and Mohammed comes after Ishmael, nobody claims Ishmael started Islam. However, Ishmael is commonly cited as being the progenitor of the Arab peoples and the link that Muslims have to Abraham.

Islam originated from Abraham's son Ishmael.
Ishmael is a character in the Bible who is considered to be the ancestor of the Arab people. He is traditionally seen as a figure of Islam, as Muslims believe that he, along with his father Abraham, built the Kaaba in Mecca.
If you are talking about the actual religion, then they are connected by the fact that both religions believe in only one God. They are also connected because they both believe in an after life. However, if you are talking about roots and beginnings, then they are connected by the fact that Abraham had two sons, Ishmael and Isaac. The Jews are a descendant of Isaac and the Arabs are descendants of Ishmael which eventually led to the two religions. The argument is who was the chosen son (that started the chosen people of God) Ishmael or Isaac. (Ishmael is older than Isaac)
Abraham was the father of Ishmael, to whom Arabs trace their ancestry.
