The Revival of the Religious Sciences by Imam al-Ghazali can be described as a book that will never die. This is because it contains a vital cognitive force that time cannot obliterate. In it the Imam discusses Islamic rulings, beliefs and character, in the style of an admonisher who understands the psyche and its secrets as well as spiritual diseases. What distinguishes this book from others is its strong spiritual influence on the reader which makes him seek both soundness of heart and his Lord's pleasure through acts of worship, rather than the mere performance of acts of worship so that they are legally valid. The book is a comprehensive encyclopaedia for all of a Muslim's religious affairs, including beliefs, acts of worship, dealings and character, as well as for individual and societal welfare. Al-Ghazali's style is that of one who practices what he knows, one who is determined to rise from the dry, ordinary manner of teaching to one which encourages action. Abu Hamid al-Ghazali is a towering figure in Islam. His enormous influence can be summarized, in the words of Annemarie Schimmel, as the one who "teaches... only to help man to live a life in accordance with the sacred law, not by clinging exclusively to its letter, but by an understanding of its deeper meaning ... so that he is ready for the meeting with his Lord at any moment." His greatest work Ihya' 'Ulum al-Din (The Revival of the Religious Sciences), comprising forty books divided into four quarters of ten books each, has helped generations towards this end until today.

AL-GHAZALI’s adapted summary of Ihya Ulum al-Din – The Forty Principles of the Religion THE FORTY PRINCIPLES OF THE RELIGION is a comprehensive distillation of Imam al-Ghazali’s magnum opus, Ihya Ulum ad-Din (The Revival of the Religious Sciences), in which he explores the spiritual depth of virtually every aspect of Islam. This condensed work presents Imam al-Ghazali’s profound insights regarding man’s lifelong struggle to draw closer to Allah in a simple framework, providing the reader with a step-by-step tried and proven method for spiritual development. The result is an essential guide to improving one’s relationship with both the Creator and the creation and a perfect introduction to Imam al-Ghazali’s other great works.

A careful and idiomatic English translation of one of Imam al-Ghazali’s most powerful books, which shows the comprehensive depth of the Qurans teachings. Shaykh Abdal Hakim Murad (T.J. Winter) Cambridge Muslim College About the author The Proof of Islam Imam Abu Hamid Muhammad ibn Muhammad al-Ghazali (d. 1111) jurist, legal theorist, logician, theologian, and mystic was a master of both the outer and inner sciences of the Shariah who is regarded by many as the greatest Muslim thinker to have lived after the Pious Predecessors. Credited with dealing the deathblow to Aristotelian philosophy in the Muslim world and bringing authentic Islamic spirituality into the mainstream, his life and thought were extremely influential in shaping the spiritual values and practices of medieval society and are no less relevant today.

The Book of Patience and Thankfulness is the thirty-second chapter of The Revival of the Religious Sciences which is widely regarded as the greatest work of Islamic spirituality. Written by one of the most famous theologian-mystics of all time, The Book of Patience and Thankfulness discusses two of the virtues of the religious and spiritual life that are of universal interest. --

In the Principles of the Creed (Kitab Qawa'id al-'aqa'id), the second of the forty books of the Revival of the Religious Sciences (Ihya' 'ulum al-din), Abu Hamid al-Ghazali explains the fundamental beliefs of Islam, those that concern faith in God, His revelation, His messengers, and the hereafter. The scope of these beliefs includes the nature of God, Muhammad s status as a prophet, the virtues of the Companions, the events related to the resurrection and judgment, and the nature of faith itself. This presentation of beliefs goes beyond a list of creedal statements; al-Ghazali cites the scriptural foundations in the Qur'an and hadith, refers to transmitted reports from the Companions and others from the righteous predecessors, and supports these beliefs with rational arguments."
