One of the Qur'an's most important attributes is that it reached us in the very form in which it was revealed to our Prophet (saas). In: "We have sent down the Reminder, and We will preserve it"(Surat al-Hijr: 9), Allah promised to protect it.
The Divine Scriptures that were revealed before Islam lost their original forms over time; they are either incomplete or not fully accurate. In the case of the Qur'an, however, Allah placed the revelations into our Prophet's (saas) memory. In addition, after he received each revelation, the Prophet (saas) told his numerous Companions to write them down, thereby ensuring the Qur'an's preservation in its original textual form. Caliph Abu Bakr (632-634) had the Qur'an compiled into a single copy, and Caliph Uthman (644-656) had copies of it sent to important Islamic cities. The following verses explain how our Prophet (saas) tried to remember the revelations, and how Allah helped him do so:
As the verses maintain, our Prophet (saas) remembered the Qur'an in a unique way, for Allah implanted its verses in his mind. As his Companions wrote it all down while he was still alive, in compliance with His promise, each of its letters has remained unaltered since the beginning of its revelation over 1,400 years ago. Therefore, Allah's revelation has survived intact to our day.
The Qur'an's lack of any internal contradiction and discrepancy also shows that it is from Allah and is immune to change. The Qur'an is internally consistent and in full agreement with historical developments and scientific discoveries. This attribute is so certain and explicit that our Lord stated:
Many contradictions can be found in regular books. However, every word of the Qur'an is in full agreement with the others. In addition, the Qur'an provides information about previous generations, communities, different forms of administration, military strategies, and many other subjects, as well as about past and future events. The Qur'an also is in absolute agreement with historical facts as well as all developments that occurred after its revelation. For instance, the first verses of Surat ar-Rum (the Byzantine Empire) state that the Byzantine Empire would suffer a great defeat, but nevertheless would be victorious shortly thereafter, as follows:
These verses were revealed around 620, almost 7 years after the idolatrous Persians vanquished the Christian Byzantines. In fact, Byzantium had been so severely defeated that its very survival was in question. Thus its predicted victory seemed impossible to many, including the Arab polytheists.
In December 627, the Byzantine and Persian empires fought a decisive battle at Nineveh. This time, the Byzantines unexpectedly defeated the Persians. A few months later, the Persians had to make an agreement with Byzantium, which obliged them to return Byzantine territory. At the end, "the victory of the Romans" that Allah promised miraculously came true. This one example alone provides evidence that the Qur'an is the Word of Allah.
Another attribute of the Qur'an is that it contains key facts about many subjects (e.g., astronomy, physics, and biology), at a time when people knew very little about such things. The Qur'an was revealed to the inhabitants of seventh-century Arabia, whose society contained many superstitious and groundless beliefs that were considered "scientific." Lacking the technology to examine the universe and nature, they believed in legends inherited from past generations. For example, they thought that the mountains supported the sky, that Earth was flat and had high mountains at both ends, and that these mountains served as pillars to kept the vault of heaven high over their heads. The Qur'an removed such superstitions, as we read in:
Several scientific truths only recently uncovered by technology were stated in the Qur'an 1,400 years ago. Such facts are further evidence that the Qur'an is the Word of Allah. (For detailed information, see Harun Yahya, Miracles of the Qur'an, Al-Attique Publications, 2000)
The Qur'an is written in a language of such surpassing beauty and richness of reference that it transcends ordinary speech. At the time of its revelation, the poets of Arabia competed with each other to produce the best literary works. However, the Qur'an's uniquely beautiful style earned their admiration, and they could not help themselves from accepting its wondrous nature in the literary sense.
This aside, an intricate mathematical code, far beyond the ability of human intelligence, is imbedded in the Qur'an's fabric. Some related words are repeated the same number of times throughout the Qur'an. For instance: day is repeated 365 times, days is repeated 30 times, month is repeated 12 times, satan and angel are repeated 88 times, world and hereafter are repeated 115 times, summer-hotness and winter-coldness are repeated 5 times, punishment is repeated 117 times, forgiveness is repeated 234 times (twice as much as punishment), wealth is repeated 26 times, and poverty is repeated 13 times.
Such facts clearly show the Qur'an is the Word of Allah, not of humanity. It is Allah's revelation to Prophet Muhammad (saas), and has remained unaltered since it was revealed.
Allah expresses this superior attribute as follows:
