Umm,
In your questioning about "future events", you are making it seem like you expect the scriptures of God to be nothing more than prophetic words of the future. What gives you this idea?
Does the Quran only speak of future events? No.
Does the Quran not document some historical items? Yes, it does.
In fact, in your religion, there were parts of the Quran that were not even revealed until a specific event occurred in the life of your prophet and THEN, all of a sudden, a revelation comes.
Furthermore, there are many, many things that took place in the early community of Muslims that was not written down or predicted in the Quran. The point of scripture is NOT to predict every single event that will occur in every single community of believers.
You don't expect the Quran to do this, so why do you expect it from the Bible?
