Islam provides definite guidelines for all people to follow in all walks of life. The guidance it gives is comprehensive and includes the social, economic, political, moral and spiritual aspects of life. The Qura'n reminds man of the purpose of his life on earth, of his duties and obligations towards himself, his kith and kin, his community, his fellow human beings and his creator. Man is given fundamental guidelines about a purposeful life and then he is left with the challenge of human existence before him so that he might put these high ideals into practice. In Islam, man's life is a wholesome, integrated unit and not a collection of fragmented, competitive parts. The scared and secular are not separate parts of man: they are united in the nature of being human.
