you told me that muslims could alter the quran. Show me your evidence for this assumption.
The Quran is just a book. Books can be altered. I'm not sure what your asking for proof of here.
This is not just any old book of words to Muslims. Stop being so ignorant. This "book" holds the unalterable word of their god.
Of course Muslims could alter the quran.
Prove it
As I said I'm not sure what proof you need that books can and sometimes are edited, poorly translated or deliberately altered between printings.
You haven't even thought this through have you.
So why don't YOU for a start, explain to Muslims how they can alter the unalterable word of the god without committing blasphemy?
How about starting here?
First, majority of Muslims would have to be be persuaded that Quran is not the literal speech from the voice of their God, but inspiration invoked in a simple man which he interpreted it in his own imperfect understanding and the understanding of his time and place.
But wait!!!!!
To that will come the extremely big obstacle that Quran and the hadith is very much believed by the absolute majority of Muslims to be the literal speech of an omniscient god . The angel Gabriel coming down to Muhammad with the quranic verses is too much a part of the faith and the scripture for it be omitted or altered, and any talk of the quran not being the literal word of God has never and will never gain the support of the majority.
What about trying this then?
Persuading the majority of Muslims that Quran was sent only for a specific time and place and the actions of Muhammad were valid only for that time?
But wait!!!!!
But Quran is believed to be the final and perfect message to all of mankind, that being another inherent aspect of Islamic faith and the scripture,it has never changed and very unlikely to ever do.
OK what about this?
Persuaded Muslims that parts of the scripture are morally wrong, and should be rejected?
But wait!!! again!!!!!
That would mean that either the omniscient, omnibenevolent god was wrong. An utterly blasphemous idea, so again, is very far from likely to gain foothold among the majority of Muslims.
So I wait with baited breath how YOU are going to explain to MUSLIMS how their holy god sent book, passed onto them PHYSICALLY via The angel Gabriel down to Muhammad can alter these sacred UNALTERABLE words?
Like I have asked you now three times now, to prove to all how THEY are going alter there book.?
