Lets put things into perspective...
Muslims believe that:
1) Muhammad is the last prophet and whatever his message is will be the last message so it is an unchanged teaching for all mankind for all time to come
2) Muslims believe Quran is perfect in its original form and does not need to be changed and there is no issue over interpretation as Quran itself says it is easy to interpret. These interpretations have already been made at time of Muhammad.
3) Quran will never change
4) Languages change over time. If you want to know the real meaning of the holy Quran you need to read the exegesis of Quran from Arab scholars from the time of Muhammad before 1000 AD and not Indian scholars from 19th century. Even Zakir Naik says that the most authentic sources are Tabari and Ibn Kathir. This shows that you are completely ignorant about your religion and the beliefs you have about Islamic knowledge are in the minority.
If you are claiming that exegesis change as science changes, doesn't that defeat the point of having an exegesis in the first place? The point of the exegesis is to prevent corruption in the word and keep the original meaning of the word and explain it in context with why the verse was revealed. You need to study your own religion before commenting.
The exegesis will change. That doesn't mean the Holy Quran is changed. There are two types of verses in Holy Quran - please get it in your fucking head (i am sorry i try to be as polite as possible but you act so damn thick sometimes and then act like you know Islam).
Muhkamat and Mutashabihat.
<<Allah is the One Who has sent down to the Prophet the Book that contains muhkamat ayat, which are the foundation of the Book, and other ayat which are mutashabihat. Those who have perversity in their hearts, they follow the mutashabihat ayat seeking discord and searching for unbefitting meanings based on their delusions. No one knows their true meanings except Allah and those who are firmly rooted in the knowledge of the Religion. The latter say, “We believe in it, all of it is from our Lord and none will understand the message except men of comprehension>>.
سورة آل عمران – سورة 3 – آية 7
We Muslims believe that the verses about simile - the true meaning is only known to Allah and we don't know their correct meaning but believe in them. There are words in Holy Quran - the meaning of which nobody knows but Allah (SWT) like Noon, Qaf, Swat at the start of Holy Quran. They're a part of the numerical miracles of Holy Quran.
The language in Holy Quran is superior to any exegesis and translation and this is why Muslims learn Holy Quran by heart in Arabic even if we don't know the meaning and don't allow the mistake of even a "zair, zabar" - grammar or pronunciation. The exegesis when it concerns the mutashabihat verses will change because only Allah knows the true meaning.
This is very evident about the verses about black holes. The Arabs at the time didn't know about black holes and there are even few words and verses which aren't even translated or exegesis provided for them except said Allah knows best. Today, we know some of them point to black holes.
This is pretty basic Islam. I don't know how you claim to be an expert on Islam and not know this simple fact.
We Muslims believe that only Allah knows the true interpretation and meanings of Holy Quran and even the people who did the exegesis clearly say that ONLY ALLAH KNOWS BEST!. No person doing the exegesis will ever claim his is the right.
Explaining this shit to you is when i lose my patience. Why don't you go and fucking ask an Imam in a mosque about this. But nay, this shows your intentions. Even the Holy Quran says that people in whose heart is a disease will find fault in these verses.
We can only try to understand them based on our limited knowledge but ONLY ALLAH KNOWS their true meaning. I think it's extremely dishonest of you to attack some person who did an exegesis to the best of his knowledge and even clearly mentions that he's not the end say in all of this. No Muslim will ever claim this.
