Abstract

The Quran, Islam’s holy scripture, is revered by Muslims as the final revelation from God – one that is complete in its guidance and thorough in its detail. This article explores how the Quran itself proclaims these qualities, with emphasis on key verses such as “This day I have perfected your religion for you” (Quran 5:3) and “We have sent down to you the Book as clarification for all things” (Quran 16:89). We examine the Quran’s self-description as a perfected and comprehensive guide, its role as the ultimate criterion for truth, and its status as the culmination of prior revelations. Insights from classical scholars and contemporary commentators (including Zia H. Shah MD) are included to illustrate how Muslims have understood the Quran’s completeness, clarity, and finality throughout history. In doing so, we see that the Quran encourages believers to let it be their primary guide in life – a source of divine instruction that needs no supplement – and warns against adding human innovations to what God has perfected myislam.org surahquran.com. A closing epilogue offers a thematic reflection on the enduring significance of the Quran’s completeness in the lives of Muslims today.
