The human beings are divided or separated based on the countries, religions, castes, languages they spoke and lot of other factors. So everyone will say that they are the best in all the aspects. But we know that this is not true. In one article, I have read that the Jews are the brainiest people in the world. This is what the Quran also says. But remember that the Quran had given to the followers of Almighty ALLAH some 1400 years ago. Are you wondering or not believing? Yes this is 100% percent true. Just if you read the Quran once, you will not only wonder for this incident, there are lot of incidents, which stated in Quran, is happening now and yet to be happened. Let the Almighty showers his blessing on all of his followers.
