what i don't understand is that why are Muslims trying to convert what are there trying to prove that only Islam is real and every other religion is wrong? Could some one tell me that what does Islam offer which other religions don't offer
Like all universalizing religions, Islam supports and encourages converts. If one is to follow Islam, by definition, they believe that it is the truth, and therefore more accurate than other religions. While I'm not a Muslim myself, Islam is a religion that teaches morals and encourages its followers to do good works. Just as a Christian believes that Christianity is better than other religions, as one must think to be a Christian, a Muslim believes that Islam is the best and correct religion. This said, just because one person follows a different religion doesn't mean that the aforementioned person must be condemned. When in the right hands, Islam is about accepting others and encouraging them to convert, rather than condemning those who don't.
