An important part of The Revival of the Religious Sciences, the Book of Patience & Thankfulness is a detailed discussion of the two qualities central to all faiths. Ghazali defines patience and thankfulness, their different forms, degrees and applications. And, he discusses the meaning of tribulation and blessings in connection with the virtues.

Al-Ghazali on Patience and Thankfulness is a translation of the thirty-second chapter of The Revival of the Religions Sciences (Ihya'' ''Ulum al-Din). This chapter falls in the section dealing with the virtues or what is conducive to salvation. Ghazali here presents definitions for patience and its different forms; the need for patience; the degrees of patience; and why patience is considered to be half of faith.

The second part of this chapter deals with thankfulness, and again Ghazali gives us definitions for thankfulness, its nature and its blessings. In addition to the translation, Dr Henry Littlejohn provides an extensive introduction which illustrates the importance of the topics of patience and thankfulness in Islam throughout the centuries.

In this new edition, the Islamic Texts Society has included a translation of Imam Ghazali''s own Introduction to the Revival of the Religious Sciences which gives the reasons that caused him to write the work, the structure of the whole of the Revival, and places each of the chapters in the context of the others.
