Abstract
The questions of human nature, being fundamental philosophical issues, have never lost their signifi-cance throughout the entire history of the development of philosophical thought. Analyzing the concept of the "perfect human" in Islam is necessary for the development of contemporary religious anthropology and for offering solutions to the problems of comprehensive human studies. The article examines and reveals the essence of such concepts as the stages of achieving perfection in Islam: spirit, intellect, heart, morals, character, and ego. Their place in the Muslim worldview is determined. From the existential philosophical perspective, the stages of transformation of human consciousness reflected in Islam are analyzed. The philosophical content of the concept of "nafs" is revealed, encompassing the unity of the concepts of soul and consciousness. The author determines that the human nature weakness hinders the full fulfillment of religious duties. To achieve the "perfect human" level in Islam, a person must go through a spiritual stage series. The article includes the study of the third education - the education of lust, which combines faith and Islam as its title. The author proves the relevance of the teaching on the cultivation of nafs in Islam in the modern era, linking it to the method of self-education in psychology. The knowledge of the conditions of faith by Muslims and their belief do not fully reflect in their behavior in everyday life. Because of the ignorance of one`s ego a person's inner faith, i.e. faith, and Islam are not interconnected. The article aims to form a correct religious understanding, emphasizing that Islam includes not only strict rules limited to external forms but also places special importance on the inner world and spirituality of the person. The author draws conclusions by analyzing the valuable works of Kazakh thinkers and for-eign scholars written in this field.
