Please enlghten me, why this doubt comes to you? What do you know about Islam? Who is a muslim? Anyway i humbly would like to furnish my opinion. One meaning of Islam is submission to God (Allah The Almighty). One who declares his beliefe in oneness of Allah he becomes muslim. Quran and teachings of Prophet PBUH guides the life a muslim. Allah the Alimighty only knows whether one lived according to islam or not. Allah The Almighty has all powers. Punishing and forgiving is all according to His (Allah the Almighty's) wish
