Question is as Following.
you said that a man becomes muslim by accepting islam .the question is that
what does the acceptance of islam signify? does it mean that whoever makes a verbal
profession;I M MUSLIM or i have accepted islam or does it mean that just a brahmin worshipper recites a few mantras of SANSKRIT without understanding them. if in the same way a man utters
some phrases of ARABIC without understand them he than and there becomes a MUSLIM?
now u many tell what reply will u give to this question.N aturally u will answer that the meaning of accepting islam is that a man should consciously and deliberately accept what has been taught by
 MUHAMMAD P.B.U.H and act accordingly, whosoever does this ,is a Muslim and whosoever does no do this, is not a MUSLIM.
