One in every five persons on this earth firmly believes that the Prophet Muhammad (Pbuh) is the last Messenger of God. He was a Muslim and there are more than 1.3 billion such Muslims today.Not only individuals but entire countries take pride in declaring their allegiance to him. There are 54 such Muslim states today, ranging from those as large as Indonesia and Bangladesh, with populations of 200 and 125 million respectively, to those as tiny as the Maldives or Brunei with populations of 230,000 and 260,000. Even in non-Muslim countries, large Muslim populations constitute significant minorities; as much as 120 million in India and 20 million in China. Indeed, within the last half century, Islam, the religion brought by the Prophet Muhammad (Pbuh), has become the second largest religion in most European countries, as also in America and Canada.
