Abram's wife Sarai had not borne him any children. But she had an Egyptian slave woman named Hagar, and so she said to Abram, "The Lord has kept me from having children. Why don't you sleep with my slave?Perhaps she can have a child for me." Abram agreed with what Sarai said... Abram had intercourse with Hagar, and she became pregnant."- Genesis 16:1-4

"Hagar bore Abram a son, and he named him Ishmael"- Genesis 16:15

Ishmael Born 1800 BCE Died at age 136 Mecca, Arabia

However; approx 13 years later, Sarah conceived Isaac with whom God established his covenant. Isaac became Abraham's sole heir while Ishmael and Hagar were banished to the desert, though God promised that Ishmael would raise up a great nation of his own.

God said "I will bless him [Ishmael] and give him many children and many descendants. He will be the father of twelve princes, and I will make a great nation of his descendants"- Genesis 17: 20

Ishmael is recognized as an important prophet and patriarch of Islam. Though little is said about him in the Qur'an itself it does suggest that he assisted Abraham in building Islam's most sacred structure, the Kaaba, in Mecca (2:127)

We are now beginning to see the biblical connection and relation between two of the most celebrated religions in the world Christianity & Islam. In the next few passages of Genesis the division becomes apparent.
