Islam is the religion of about 1.7 billion people all over the world. It is believed by Muslims that Islam is the original faith sent down and prescribed by Allah (God) the Almighty for all humanity since Prophet Adam (Peace and blessings be upon him). To them, it is not a mere faith or religion sent down by Allah to Prophet Muhammad, the last Prophet, (Peace and blessings be upon him), rather, it is the faith of all prophets and messengers and the faith of fitrah (natural disposition) and that many people exchanged it for either disbelief or belief in other than Allah, the Creator of everything.
