Allah created man as his vicegerent and made him superior to every living and non-living creature that He created from nothing. The first condition of the vicegerency is to have faith. Faith is a whole with its constants and changes in every age. The constant of faith is La ilahe illallah, the perfect word, and its changeable part is the Honorable Being (the exalted ones, the Messengers and Prophets) in whose era we are living. The light of faith that started with Hazrat Adam Safiyullah Aleyhisselam continues to enlighten us brightly today with our Sultan Ahmed-i Muhtar Sallallahu aleyhi ve Sellem. Since the light of faith is a whole, faith and Islam without a prophet is not possible. Therefore, without saying la ilahe illallah Muhammad Rasulullah, we neither believe nor gain the title of caliphate of Allah. Being caliphate of Allah is to be a Muslim and to be a believer. In other words, believing is to sign a contract. The provision that is the umbrella within the terms of the contract is to accept to take the test. People are subjected to various tests according to their own permissions. Permission is the name of the material and spiritual blockage that a person or his descendants experience in their life, soul and body within the framework of that sin as a result of the sins committed. Getting a permit is to become prone to the same or similar sins, mistakes, diseases, troubles and troubles as a result of the material and spiritual blockage experienced. Those who make mistakes due to heedlessness during the tests deserve (Punishment and They will encounter a result that will be defined as "trouble". The deservings (diseases, troubles, troubles) that come to them as a result of wisdom are from Allah's mercy and include the following message "Come to your senses and pull yourself together while you still have time". Whether the deservings are from lineage or the work of a person's two hands, they can be detected and resolved. The solution is possible with repentance. Spiritual rehabilitation is the science of detecting the bad and harmful deservings that are related to people's lives, souls, bodies and souls, and cleansing the person from both the burdens of lineage and the material and spiritual deservings that they have made with their own hands, with certain religious principles. This science is a spiritual science that has emerged as a result of the principles put forward by the Holy Quran, the Sunnah of the Prophet and the saints.
