Ishmael was the first son of Abraham. 
Ishmael was born to Abraham and Sarah 's handmaiden Hagar (Genesis 16:3). According to the Genesis account, he died at the age of 137 (Genesis 25:17). The Book of Genesis and Islamic traditions consider Ishmael to be the ancestor of the Ishmaelites. Share to: Hagar is the maidservant of Sarah(Sarai),, sarah gave hagar to abraham, because sarah is barren, she cannot gave abraham a child, so sarah gave her maidservant, hagar, to him … , so they had their relationship then they had son, named ISHMAEL, HAGAR's son to Abraham. So, according to the Book of Genesis, Ishmael and Isaac are the sons of Abraham, and they’re half brothers. Abraham’s wife Sarah can’t bear children, so she lets Abraham sleep with her maidservant, Hagar, who gives birth to Ishmael. There are at least two people in the Bible named Ishmael. The name is sometimes translated into English as Ishmail. The first and most famous was Ishmael, son of Abraham. Another was Ishmael, the son of Nethaniah, best known for killing Gedaliah, who had been appointed as governor of Judah. He was Abraham's first born son who's birthright was given to his younger brother Isaac instead. Isaac was born to Abraham's favorite wife Sarah and Sarah demanded that Ishmael and his mother Hagar be cast out into the desert to die, so Abraham cast them out. Fortunately though, God saved them from dying. Ishmael was the first son of Abraham. His mother was Hagar, who was the Egyptian handmaid to Sarah, who was Abraham's wife. Ishmael was the half-brother of Isaac, who was the son of Abraham and Sarah. Sarah had been unable to have children. So she presented her maid, Hagar, to Abraham to bear an heir for Abraham. Hagar gave birth to Ishmael when Abraham was 86 years old. Fourteen years later, Isaac was born.
