The Divine Letters
In the previous chapter, we discussed how God chose specific human beings to act as His trusted messengers. If the prophets are the messengers, the holy books are the actual, direct letters they were entrusted to deliver. In Islam, a holy book is a divine revelation—God's exact words, spiritual laws, and practical guidance—sent down from the Creator to a specific prophet, who was then tasked with sharing every single word with their community.
The Ultimate Instruction Manual
While the prophets provided a living, breathing example of how to act in everyday life, the holy books provided the permanent, objective standard of truth. They were given to humanity so that we wouldn't have to guess our ultimate purpose, how to build a just society, or what happens after we die. They were sent to serve as a permanent compass, ensuring that even after a prophet passed away, the people would still have a clear, reliable guide to tell right from wrong.
Islam requires its followers to believe not just in the Quran, but in all the original divine books sent down by God before it. While the Quran mentions that many prophets received scriptures, it specifically highlights four major books by name:
The Tawrat (The Torah)
The Tawrat was revealed to Prophet Musa (Moses). In its original form, it contained the laws, commands, and guidance for the Children of Israel. The Quran speaks of the original Tawrat with deep respect, describing it as a source of brilliant light and spiritual direction for its time.
The Zabur (The Psalms)
The Zabur was given to Prophet Dawud (David). Unlike the Tawrat, which was heavily focused on practical laws and societal rules, the Zabur is traditionally understood to be a collection of beautiful, poetic hymns and songs of praise used to worship God.
The Injil (The Gospel)
The Injil was revealed to Prophet Isa (Jesus). It was sent to confirm the truth of the Tawrat, soften some of the stricter laws that had been placed on the Israelites, and provide fresh spiritual insight. Muslims believe the original Injil was the direct word of God given to Jesus, rather than biographical accounts written about him by other people later on.
The Quran
The Quran is the final revelation, given to Prophet Muhammad ﷺ over a period of 23 years. Unlike the previous books, which were sent to specific nations for specific periods of time, the Quran was sent as the universal, permanent guide for all of humanity until the end of time. It serves as both a continuation of the previous books and a final filter to correct where human beings altered the older messages.
Lost in time and translation
Islam teaches absolute respect for the original revelations given to Moses, David, and Jesus. However, Muslims believe that those original texts were not perfectly preserved over the centuries. Before the printing press, scriptures were copied entirely by hand and translated across multiple ancient languages. Because those early communities did not have a widespread, heavily regulated tradition of memorizing their entire holy books letter-for-letter, parts of the original messages were naturally lost, forgotten, or mistranslated over time.
Human alterations
Beyond simple copyist errors, the Quran states that over hundreds of years, some religious leaders intentionally altered the texts. They changed rules, added their own historical accounts, or removed verses to suit political agendas or cultural pressures. Over generations, these human words and opinions became permanently mixed in with the divine words.
Fragments of truth
Because of these changes, Muslims believe that while modern versions of the Torah and the Bible still contain beautiful, profound fragments of the original divine truth, they can no longer be considered the exact, 100% uncorrupted words of God. Today, they are viewed as a mixture of original revelation, historical biography, and human additions.
The Final Correction
Because the previous scriptures were altered or partially lost over centuries, God sent the Quran to serve as the ultimate, final correction. You can think of it like the finalized, master version of a critical document. It confirms all the original, unchanged truths from the Torah and the Gospel—like the absolute oneness of God and the importance of helping the poor—while permanently correcting the human additions and theological mistakes that had crept into those older religions over time.
Divinely Protected from Change
The biggest difference between the Quran and the older holy books is the guarantee of its preservation. With the previous scriptures, God left the responsibility of protecting the texts to the religious scholars and rabbis of those specific eras, and human error eventually took over. However, because the Quran is the absolute final message to humanity, God explicitly promised in the Quran itself that He would personally protect this final revelation from any corruption, addition, or subtraction until the end of time.
A Universal Guide
The earlier books were highly localized. They were sent to specific tribes and specific nations to address the unique problems of that exact time period. Because they were temporary, their eventual alteration wasn't the end of the story; God simply sent another prophet. But the Quran was sent to the entire world. Because there will be no future prophets to correct new mistakes, this final holy book was designed to be universally applicable for all cultures, all places, and all generations.
Does Islam say the Bible and Torah are completely false?
Not at all. Islam teaches that the original Torah and Gospel were absolute truth, filled with beautiful guidance and light. Even in their current forms, Muslims believe these books still contain many accurate fragments of God’s original message. When a Muslim reads the Ten Commandments or the teachings of Jesus to love one's neighbor, they recognize it as divine truth. However, because human words and historical changes have been mixed in, Muslims do not take the entire modern Bible or Torah as the literal, uncorrupted word of God. The Quran simply acts as a filter: whatever in the older books matches the Quran is accepted as original truth, and whatever contradicts it is considered a human alteration.
Why trust the Quran over older scriptures?
The biggest difference comes down to historical preservation and authorship. With the modern Bible, historical scholars openly acknowledge that we do not have the original manuscripts, the original language of Jesus (Aramaic) was lost in translation to Greek, and the exact authors of many biblical books remain completely unknown. In contrast, the Quran has a verifiable, unbroken chain of preservation. Millions of people alive today have memorized it cover-to-cover in its original Arabic, exactly as it was spoken by Prophet Muhammad ﷺ. If every holy book on earth were burned today, the Quran is the only one that could be perfectly rewritten from memory by tomorrow morning.
Can Muslims read the Bible or Torah?
Yes, Muslims are allowed to read previous scriptures for historical context, interfaith dialogue, or out of general interest. In fact, early Islamic scholars frequently referenced them. However, they are read with the understanding that they are no longer purely divine texts. Because the Quran was sent as the final, perfectly preserved update to humanity, Muslims rely entirely on the Quran and authentic Hadith for their theology, religious laws, and daily spiritual guidance.
