The third book discusses zakat and grants which consists of 4 chapters with 60 articles and the fourth book on Sharia Accounting which consists of 7 chapters with 62 articles. This article was compiled using a qualitative descriptive method to explain the 13 principles in KHES. The principles of the contract include ikhtiyari, amanah, ikhtiyati, luzum, mutual benefit, taswiyah, transparency, ability, taisir (ease), good faith, halal cause, al hurriyah (freedom of contract) and al kitabah (written). Of these thirteen principles, all of them are intended so that every contract that occurs in the economic sphere can run according to sharia, can bring benefits and avoid all forms of omnipresence.
