The Quran is the holy book of Islam. It is important to remember that the quran in english is a best effort translation and not the direct word of god. As god stated in the -Quran in Chapter (41) Verse (3) (An Arabic Quran for a people who know). The English Quran gives you a direct translation of the holy Arabic words, I strongly recommend reading Tafseer to get a better understanding for the meaning of the verses. and to understand the words in context.
If we had sent down this Qur'an upon a mountain, you would have seen it humbled and coming apart from fear of Allah . And these examples We present to the people that perhaps they will give thought. (Surah 59) (Aya 21)
