Why is Abraham important? Pls i need help asp

Abraham, Hebrew Avraham, originally called Abram or, in Hebrew, Avram, (flourished early 2nd millennium BCE), the first of the Hebrew patriarchs and a figure revered by the three great monotheistic religions—Judaism, Christianity, and Islam. According to the biblical book of Genesis, Abraham left Ur, in Mesopotamia, because God called him to found a new nation in an undesignated land that he later learned was Canaan. He obeyed unquestioningly the commands of God, from whom he received repeated promises and a covenant that his “seed” would inherit the land. In Judaism the promised offspring is understood to be the Jewish people descended from Abraham’s son, Isaac, born of his wife Sarah. Similarly, in Christianity the genealogy of Jesus is traced to Isaac, and Abraham’s near-sacrifice of Isaac is seen as a foreshadowing of Jesus’ sacrifice on the cross. In Islam it is Ishmael, Abraham’s firstborn son, born of Hagar, who is viewed as the fulfillment of God’s promise, and the Prophet Muhammad is his descendant.
