Which of the following best describes the Quran?

The Quran is regarded as the holy book of Islam and is fundamentally characterized by its belief as the direct word of God, revealed to the Prophet Muhammad through the Angel Gabriel. This sacred text serves as a comprehensive guide for Muslims, covering various aspects of life, law, morality, and spirituality, making it central to the Islamic faith.

While options such as the philosophical treatise on ethics or the historical account of Islam's early days touch on specific themes that may be present within the Quran, they do not encapsulate its essence or primary purpose. Similarly, while the Quran contains passages that can be utilized in prayers and ceremonies, it is far more than a mere collection of prayers; it's a complete religious and spiritual guide that shapes the beliefs and practices of Muslims. Thus, the identification of the Quran as the holy book of Islam reflects its significance and the reverence it holds in the hearts of believers.
