Quote from : Islam: The Concept of Religion and The Foundation of Ethics and Morality Book

Change, development and progress, according to the Islamic viewpoint, refer to the return to the genuine Islam enunciated and practised by the Holy Prophet (may God bless and give him Peace!) and his noble Companions and their Followers (blessing and peace be upon them all!) and the faith and practice of genuine Muslims after them; and they also refer to the self and mean its return to its original nature and religion (Islam).
