The word Amen is a word used by Muslims and Christians. Muslims used the word first and was pronouced Ameen. after the Christians got a hold of it, it became Amen. Muslims to this day say Ameen, Christians say Amen.
(Ameen and Amen are both said at the end of both the Muslim and Christian version of Grace)
Muslim: In the name of god, most gracious, most merciful, ameen.
