Al-Ghazali was a Muslim theologian, jurist, philosopher and mystic of Persian origin. He was born in 1058 AD in Khorasan, Iran. He received his early education from Baghdad and Nishahpur where he received high scholarship in the field of religion and philosophy. For his efforts, he was appointed professor at Nizamiyah University in Baghdad, which was recognized as the greatest institution of learning during the "golden era of Islam". Belonging to the Sunni denomination, Al-Ghazali practiced Shafi jurisprudence and associated himself with the Asharite school of thought. He was a key member of the Asharites and the chief refuter of the Mutazilites. However, his opinions and thoughts differed from the Asharite orthodox school of thought. There came a point in Al-Ghazali's life when he became involved in a process of mystical transformation and abandoned his academic pursuits. He gave his wealth to his family and went to Mecca for the pilgrimage. He began to live in isolation and wandered like an acetic. Therefore, an era of solitary life was devoted to contemplation and writing which produced many eternal books. Ghazali's main interests were Islamic jurisprudence, theology and Sufism. In an era when Greek philosophy influenced many Muslim thinkers, Al-Ghazali believed that Neoplatonic philosophy was primarily in conflict with Islamic teachings. On the other hand, Sufism was also evolving into non-Islamic beliefs. Ghazali with his knowledge and personal mystical experience set out to rectify these tendencies. In philosophy, Ghazali wrote a book titled "The Inconsistency of Philosophers".

Al-Ghazali wrote more than 70 books on the sciences, Islamic philosophy and Sufism. He wrote most of his works in Arabic and some in Persian, including "The Alchemy of Happiness". William Montgomery Watt agrees that Ghazali was a resuscitator of his era. Ghazali's profiled writing had an enormous influence on Jewish and Christian scholasticism. Many Christian philosophers have used his arguments to restore the authority and orthodoxy of their religion. His argument for religion is considered so strong that it is assumed to have damaged the cause of philosophy. Ibn-Rushd even wrote a rebuttal to Ghazali. Although this argument has been contested, Ghazali had already set the course of Islamic epistemology..
