This book on Sufism explains three of the four controversial issues mentioned by Sheikh Abdul Karim al-Jili in his book "Al-Insan" (The Human Being), which is "Al-Insan al-Kamil" (The Perfect Human Being) in the knowledge of the first and the last. These issues are: the question of creating things from nothingness; the question of calling God "the Free One"; the question of whether God's knowledge is derived from the requirements of information or from an original knowledge from Him; and the fourth question is whether God's essence is perceptible or only His attributes.
