In A Treasury of the Quran, Maulana Wahiduddin Khan explains that the Quran, according to Islamic belief is the preserved word of God sent for all mankind. This book comprises excerpts from the Qur’an, arranged under relevant headings. It provides an introduction to Islam, which is derived directly from the original, revealed source. No interpretation or commentary has been added. The theme of this book-the good life-is taken from the following verse of the Qur’an: Be they men or women those who believe and do what is right, We shall surely endow with a good life: We shall reward them according to their noblest actions (16:97). The meaning of the "good life" mentioned in this verse is clear from the phrase "according to their noblest actions." A good life is a life of good actions. A commentator of the Qur’an, ad-Dahhak, has defined it as "being content with an honest living and serving God in one's life." This is the meaning that the Companions of the Prophet and their followers generally inferred from the phrase. The Qur’an has given a clear exposition of the theoretical and practical nature of the good life. The verses which have been selected for this book describe various fundamental aspects of this life in the Qur’an’s inimitable style. These passages thus provide both a description of the good life and an authentic example of how it should be lived.
