<p>The history of the Semitic Religion tells us people belonging to world's three great monotheistic religions Judaism, Christianity and Islam have inherited their faith from Abraham. Their holy scriptures-both Bible and Quran also mentioned Abraham as the father of many nations. He was also called the friend of God because he overcame many difficult trials as it is believed by the Jews, the Christians and the Muslims equally, is to sacrifice his only son of his old age by the command of God. </p><p><br></p><p>They also believe equally God commanded Abraham to stop when he was ready with a knife to kill his tied-up son inside a thick bush. They also believe equally he was provided with a ram and commanded to sacrifice it in place of his son. But one thing they have differed completely is about the intended son of his sacrifice.</p><p><br></p><p> Both the Jews and the Christian claim the intended son of Abraham's sacrifice is Isaac- his younger son through his wife Sarah while the Muslims claim he is Ishmael-his firstborn through his second wife Hagar- Sarah's Egyptian handmaid. This book describes in detail how or why this difference or discrepancy in their claim occurred based on the statements of the Bible, the Quran and the narration of the Judeo-Christian and Islamic Tradition.</p>
