Which religious text is recognized as the holiest scripture in Islam?

The Quran is recognized as the holiest scripture in Islam because it is believed to be the literal word of God (Allah) as revealed to the Prophet Muhammad through the angel Gabriel. Muslims regard the Quran as the final and complete revelation in a long line of divine messages that have been sent to humanity. It serves as a guide for personal conduct, spiritual practice, and the legal and ethical framework for the Muslim community.

In contrast, the Torah is a sacred text in Judaism, containing the laws and teachings central to Jewish faith. The Bhagavad Gita is a significant Hindu scripture that addresses important concepts like duty, righteousness, and devotion. The Upanishads are a collection of philosophical texts that form the basis of various Hindu philosophies, focusing on meditation, morality, and the ultimate nature of reality. While these texts are vital to their respective religions, they do not hold the same position within Islam that the Quran does.
