Gramasam: Abraham was a muslim: one who surrenders to God.

GodofVice007: Impossible, mohammed wasn't born yet, hence moslems didn't exist.

RKC: I don't think you understand the definition of what a Muslim is. A Muslim is not only someone who follows Muhammad(p), but someone who follows any Prophet. A Muslim is someone who, as Gramasam said, one who surrenders their will to God.

Surah 22

77. O ye who believe! bow down, prostrate yourselves, and adore your Lord; and do good; that ye may prosper.

78. And strive in His cause as ye ought to strive, (with sincerity and under discipline). He has chosen you, and has imposed no difficulties on you in religion; it is the cult of your father Abraham. It is He Who has named you Muslims, both before and in this (Revelation); that the Messenger may be a witness for you, and ye be witnesses for mankind! So establish regular Prayer, give regular Charity, and hold fast to Allah. He is your Protector - the Best to protect and the Best to help!

129. "Our Lord! send amongst them an Messenger of their own, who shall rehearse Thy Signs to them and instruct them in scripture and wisdom, and sanctify them: For Thou art the Exalted in Might, the Wise."
