Answer:
The system that directly links an Islamic country's laws with the principles of the Quran is known as Shariah.
Step-by-step explanation:
Shariah is the body of Islamic law. It constitutes a detailed code of conduct, which also includes the rules relating to the ways of worship, the criteria of morality and life, the things allowed or forbidden and the separating rules between good and evil. However, its identification with religion is nuanced: although it is in Islam, it is not a dogma or something indisputable (as could be the text of the Quran), but an object of interpretation.
