So far in my studying of Islam, it seems that there are a tonne of books in the Islamic community that are referenced often and commonly. My question is, how can I tell which are the more "official" books (like the Quran) and which are more opinionated (such as ones written by scholars and the such)?
P.S. I mean no disrespect by my wording in this post, I just don't have the vocabulary to word it in a more precise manner.
Like some of the posters above already said:
The Quran is the primary book of information. It is directly revealed by God. There is only one version of it, so you can take every Quran you find...of course in original language, which is Arabic. If you choose to read a translated version of the Quran...you must know that not every text can be translated equally accurate...so that is one point to take in consideration.
Then, you have the Hadeeth. Those are recordings of people who have known, met, saw, heard the Prophet Muhammed.
The Hadeeth is man-written and not all hadeeth are equally reliable. if several different people have recorded the same event, then it is a strong hadeeth. event recorded by only one person are usually weak hadeets.
Bukhari was a person who dedicated his life on collecting these hadeeths. It is said that he did a 2 rakaat salaah for every collected hadeeth to ask God to help him with collecting the truthworthy hadeeths. and he collected tens of thousands of them.
Usually Hadeeths collected by Bukhari and Muslim are reliable. then the other Hadeeth collections.
Then you have book who provide you background information about the Quran. These are called Tafsirs. They provide information like, when a verse was revealed first, what whas happening in the world at that time, the motive of the verse, a translation in your language, how a certain word in this verse should be interpreted. For what I know, the most reliable Tafsir is from Ibn Kathir.
I personally find the Tafsir a very important book to understand the Quran better.
