[Ali Imran]

Which interpretation truly reflects the word of God? The term Muhaymin can mean guardian, witness, or even the supreme authority. If the meaning remains ambiguous, Moslems might become radicalized, believing that Islam holds absolute supremacy over other religions.....

So should we trust the Quran with many interpretations to be the word of God? The short answer is No! Because there is no clear direction or answers

The Quran is the word of God, verbatim. When the Quran states the universe is expanding, 1,400+ years ago, we only know today that the universe is indeed expanding. Was it critical for Muslims 1,400+ years ago to know that for a fact? The answer is no, it wasn't necessary. 

Is it critical for us to know what really happened to the son of Mary on that day? No, we don't need to know.

Can we Muslims trust the Quran? 100% yes. We believe it is 100% the word of Allah and Allah has assured us that it will remain as our guidance till the end of time.
