This is an interesting post that gives Muslims instructions on why the Qur’an should be more central in their lives and how they are to approach it. Since the Qur’an is so central to Islam and to the lives of Muslims, it is helpful for non-Muslims to better understand it. I encourage you to read the article and get a flavor for how Muslims see their holy book. I also would encourage you to read the Qur’an itself.
Here are some quotes:
You must approach the Quraan with an open mind so to allow the Quraan to speak for itself. You cannot approach the Quraan with the mentality that you already know the truth, as this will cause you to try and twist the Quraan to meet what you want to believe.
Don’t discard half or a third of the Quraan thinking it is not relevant to you, rather take the time and look for this guidance yourself. You are holding and reading the words of Allah ta’ala himself. He did not give us this book baatila or in vain, but He gave it to us to save ourselves.
You will begin to understand more and more lessons of the Quraan when you begin to live the Quraan. On the other hand, one of the things that will take away your guidance and knowledge is the committing of sins. The more sins you commit, the less you will understand the Quraan. It is a dynamic relationship. The more you turn to Allah, the more Allah turns towards you.
