Prophet abram and Muhammad

From Wikipedia (http://en.wikipedia.org/wiki/Islamic_view_of_Abraham):

Ibrāhīm (Arabic: ابراهيم, Hebrew: אַבְרָהָם) , the biblical patriarch Abraham (circa born between 1900 BC to 1861 BC - died between 1814 BC to 1716 BC), is an important prophet in Islam. He is the son of Azar and the father of Ismail (Ishmael) -his first born son- and Is'haq (Isaac) his second born, both of whom are considered Islamic prophets. Ibrahim is considered the Father of the Prophets. Ibrahim is commonly termed Khalil Allah, or "Friend of God" or "Braheem".
Islam regards many sorts of the biblical patriarchs as prophets of Allah, and hence as Muslims (i.e., monotheists). Ibrahim is regarded as a Hanif (meaning a discoverer of monotheism without being taught by a messenger).
Because of their mutual veneration for Abraham, Islam, Christianity and Judaism are sometimes summarized under the term "Abrahamic religions".
