Abhinav it would have been better if you have given us the whole context of the passage from where you got it.Simply reading a website which is built to defame islam(which cannot be)is useless.We muslims know the context.If you have a clear heart and a mind which wants to know the truth you will explore islam from authentic sources and question the ones who can answer your questions.You can have an elobarate discussion with scholars at irf.net they might help you in getting rid of your misconceptions and help you in knowing the true submission to one almighty.
