Islam is a religion of justice, peace, mercy and forgiveness. Muslims believe in the ONE TRUE GOD (ALLAH) and follow the SUNNAH (teachings) of the Prophet Muhammad (peace be upon him) and the QUR'AN (the last holy book) which was sent down to the Prophet Muhammad (who was unlettered) from ALLAH through the Archangel Gabriel. It was recorded and memorized by many at that time and is still memorized by thousands of Muslims all over the world today. The Holy Qur'an has remained unchanged, even to a dot, over the past fourteen hundred years. One of the hallmarks of Islam is its complete harmony with science. There has never been a scientific fact or a valid scientific theory that contradicted the teachings of Islam. It deals with every subject - morality, knowledge, science, law, systems of social justice, politics, economics and directions for every sphere of life. It is a book of wisdom and guidance through which Allah, (Most Gracious and Most High) speaks to humanity. The Qur'an was completed during the life of the Prophet Muhammad (peace be upon him) yet contains profound knowledge of science and medicine that was centuries ahead of its time.
