Ishmael was not the promised son from God. Ishmael came about because Sarah gave Abraham Hagar to produce a son thinking that they would help God out with His promise of a son. A big mistake. Abraham was 86 years old when Ishmael was born.
Abraham was exceedingly happy when Ishmael was born and wished that Ishmael would be the child of promise, showing little faith in God's abilities. But God corrected Abraham and told him that his son Isaac will fill that role. He had other plans for Ishmael:
The handmaid's name was Hagar. She was Sarah's servant, and Abraham had a child with her named Ishmael in order to fulfill God's promise of descendants.
The Ka'bah is the House of God built by Abraham and his son, Ishmael, for the worship of the One God. It is "The Ancient House". It was built as part of God's promise to bring a Prophet from the descendants of Ishmael.
Issac was the son born to both Abraham and Sarah., while Ishmael was born to Hager.
AnswerThe Israelites believed that God had made a promise to Abraham that his successors would inherit the land of the Canaanites. This would have included other, non-Hebrew people such as the Arabs, said in The Bible to be descendants of Ishmael, so the promise or covenant was later refined to include only the descendants of Israel.
Because Abraham being the father of their family. Ishmael was Abraham's first born son, thus following Hebrew tradition, should have received the blessings of the father. However, because He was not the son of promise, Abraham had to follow the dictates of God. This is the forerunner for the gospel of Jesus Christ.
In the book of Genesis in the Bible, God promised Abraham and Sarah a son, even in their old age. Abraham was 100 and Sarah was 90 when Isaac was born. The "Child of the Promise" refers to God's promise to Abraham and Sarah.
When Abraham was approximately 86 years old the Lord promised Abraham that he would have an heir, and that Abraham's descendants would be as numerous as the stars and to his descendants God would give them the land from the river of Egypt to the great river, Euphrates ( Genesis 15). This was a reassurance of the promise in Genesis 12. We know that about this same time period, Sarah told Abraham to go into her handmaid, Hagar, and that perhaps they might have an heir by her. This was a mistake. Ishmael was born from this union and about 14 years later a son, Isaac was born to Sarah and Abraham. Abraham was 100 years old (Genesis21:1-7.) Isaac was the son of promise.
Abraham's original sacrifice was his son Isaac(Ishmael to the Islam religion) but God stopped him and so Abraham sacrificed a nearby ram as an offering to God.
According to the Bible, Jehovah God promised to "bless him...make him fruitful...and multiply him...very much...and..make him a great nation." (Genesis 17:16-20) This happened after Hagar (his mother) found him a wife, after which Ishmael had 12 sons just as Jehovah had said (Genesis 17:20), that would end up becoming the chiefs of the Ishmaelite nation. (Genesis 25:13-16) (New World Translation of the Holy Scriptures)
Yes, Ishmael and Esau did worship the same God as Abraham, who is considered the patriarch of the Abrahamic religions (Judaism, Christianity, and Islam). They all followed the monotheistic faith that believes in one God.
Abraham was the father of Ishmael by Hagar, the Egyptian servant of Sarah. Sarah gave Hagar as a wife to Abraham because she herself was barren. Later, Sarah gave birth to Isaac and eventually Hagar and Ishmael were sent away. Incidentally, many Muslims believe that Ishmael (or Ismail) was the son Abraham was ordered to offer up to God in sacrifice although this isn't specified in the Qur'an.
