The Qur'an contains teachings and principles that serve as a guide for Muslims in understanding what is right and wrong, just and unjust, and morally acceptable. It provides clear directives and instructions that help individuals make informed choices and judgments in various aspects of life. By following the teachings of the Qur'an, Muslims seek to align their actions and decisions with the divine guidance, ensuring that their judgments are based on the principles and values set forth in the holy scripture.
