"By faith Isaac blessed Jacob and Esau in regard to their future. "-Heb 11:20
The New Testament contains few references to Isaac. The early Christian church viewed Abraham's willingness to follow God's command to sacrifice Isaac as an example of faith and obedience.
Isaac is a prophet in Islam. A few narratives of Isaac appear in the Qur'an. The Qur'an views Isaac as a righteous man, servant of God and the father of Jews. The Qur'an states that Isaac and his progeny are blessed as long as they uphold their covenant with God. Some early Muslims believed that Isaac was the son who was supposed to be sacrificed by Abraham.
