‘Is The Quran God's Word? by Dr. Zakir Naik’ discusses the origins of the Quran and whether it is the word of God or was authored by Prophet Muhammad (may the peace and blessings of God be upon him). It presents several arguments to refute the claims that Prophet Muhammad authored the Quran, including:

1. Prophet Muhammad never claimed authorship of the Quran and always attributed it to divine revelation.

2. The Quran contains information and knowledge that was unknown at the time, making it highly unlikely that a human could have authored it.

3. The Quran provides challenges and falsification tests that no human could have met, such as producing a chapter similar to it.

4. The Quran's style, structure, and content are vastly different from anything a human could have produced, especially an illiterate person like Prophet Muhammad.

5. Prophet Muhammad's life and character are incompatible with him being a liar or deceiver who fabricated the Quran.

The audio concludes that the Quran is the word of God revealed to Prophet Muhammad, and that this is the only logical explanation for its origins and contents.
