It is a tradition that Mohammed wrote or dictated the Quran..
No, not in the same way.
It is traditionally THOUGHT that Moses wrote it. It is an ancient scripture, and we really don't have a clue.
It is purely, like
@RJM Corbet suggests, that one might think that at every step of the way, all text in the Bible has been
saved from error by Divine inspiration.
Personally, having discovered the Qur'an [ which is one revelation, and not a collection from over many centuries ],
I can see that this is not very likely.
In the interest of civility I will not go here just now.
OK .. but I'll just mention that I found the graphic descriptions of hell repulsed me when I first read them.
Coming from a protestant background, I hadn't really thought about hell .. more about heaven
Eventually, I realised that there are many people in the world who live in very harsh environments.
There is a great deal of suffering going on.
If Almighty G-d won't allow us to suffer in the next life, then why does he let us suffer in this one?
What about people who torture or oppress others? Is it justice that there are no consequences
for such evil? Clearly not.
The consequences of righteousness is success and contentment.
The consequences of evil is failure and torment.
The descriptions in the Qur'an make it very clear. It compares heaven and hell with concepts that we can
understand only too well.
It does not necessarily mean that there is "a being" who literally judges or tortures people.
We do that to ourselves.
The second point is about the order to be harsh with ones enemies [ kafir ]
These verses refer to defending the community from those who wish evil upon them.
There are many verses that instruct Muslims to make peace treaties, and to be just in dealing
with all human beings.
