Abraham is called Ibrahim by Muslims. They see him as the father of the Arab people as well as the Jewish people through his two sons, Isaac and Ishmael (Isma'il in Arabic).
The Muslim story of IbrahimAbraham is a very interesting figure because he is depicted in the Qur'an as somebody who, from a very early age, had problems trying to understand God and trying to discover God; being restless, knowing that perhaps the Pagan environment which he was in did not have the answers. That, ultimately, God was not the star or the sun or the wind or the moon - all these forces that he saw - God was in something else.
And so from that perspective, Abraham is considered to be neither a Jewish person, nor a Christian person nor a Muslim, but somebody who is a hernif - somebody who essentially and intrinsically knows that there is really only one God. And he is praised for this essential and innate yearning to discover the unity of God.
There have been thousands of prophets and numbers of messengers but there are only four or five that have been designated a specific title according to Islam: Jesus is one, Moses is one and the Prophet Muhammad is one but also Abraham, who is known as a friend of God.
Abraham had a specific allocation given to him by God, which is that from his progeny will be all the prophets and from them - for Muslims - comes Muhammad. But he does have a relationship with God: first of all he is baffled as to how he has a son at such a late stage through Hagar and then through Sarah.
The tradition of God testing Abraham's devotion to him by asking him to sacrifice Ishmael is the heart of the Abrahamic tradition and the Abrahamic stories. Abraham was the first Prophet who was asked for the ultimate sacrifice: "I want you to sacrifice your own flesh and blood for me". And he passed the test because he was prepared to do it, in his submission and devotion to God.
What are the stories told about Abraham in the Qur'an?Many of the stories in the Qur'an that relate to Abraham, Hagar and Ishmael are about their flights from Sarah and also about Abraham trying to set up another dwelling, another place with Hagar and his son Ishmael.
Much of what Islamic tradition is about - and even some of the rituals such as the Hajj - stem from the pre-Islamic era and are translated into Islamic rituals through Abraham. Hagar looked for water and ran between two hills, which is enacted in the Hajj ceremony as a symbolic gesture of what Hagar was doing - looking for water - and pilgrims do that.
God says to Abraham, "I'd like you to build my house for me..." - that is a Kaaba - "...here on this mound of earth, in this sacred place and I'd like you to erect the walls and I want you to purify this place." Part of this purification is what we see today in the Kaaba. The Islamic tradition has restricted this purity ritual to Muslims only. However the second ambulation that pilgrims do in praise of God is actually a legacy left from pre-Islamic days when pilgrims also came to the Kaaba - not to worship the one God, but to worship idols.
There are various things that are part of the Abrahamic story, culminating in the ultimate sacrifice which is carried out on the last day of Hajj. As a symbolic gesture, Muslims re-enact what Abraham was going to do with Ishmael by sacrificing a lamb or sheep.
