Which term best describes Muslims who follow the teachings of the Qur'an?

The term that best describes individuals who adhere to the teachings of the Qur'an is "Muslim." This term specifically designates followers of Islam, which is a faith rooted in the revelations contained in the Qur'an. Muslims strive to apply the teachings of the Qur'an to their lives, encompassing aspects of faith, ethics, and law as outlined within the text.

In contrast, "Mumin" refers to a believer in a broader sense but does not specifically indicate adherence to the Qur'an. "Fasiq" denotes a person who is deemed sinful or a transgressor in Islamic context, which does not apply to those following the Qur'an's teachings. "Fuqaha" refers to scholars or jurists well-versed in Islamic law and jurisprudence, which again, does not specifically capture the essence of all practitioners of Islam. Therefore, "Muslim" accurately encapsulates anyone who accepts and follows the Qur'an as foundational to their faith.
