They have managed to stay online a long time, while some of my favorites are gone, most shut down by IP hosts, hackers, and governments. I figure some sites yielded to the threats that come.
Apparently this Arthur Arberry translation is OK to share online. It's supposed to be the best Quran translation, though Muslim scholars say it can't be translated properly from the ancient Arabic.

I'm curious about claims of the Quran supporting Christianity and Judaism since it makes clear that what scriptures we have today are corrupted, unlike the original, so we can't possibly understand our scriptures, so must accept the Quran, which is claimed to correct the Torah and New Testament.
History shows Muslims typically don't expect Jews or Christians to accept it or Islam because of their corrupted minds making it difficult to embrace Islam. I've been told that many times online. It's easier for their extremists to simply demand conversion or die, knowing many will choose death. They prefer finding people who are ignorant of any religion.
There's a lot of reference in the Quran to our Bible, so if you are patient and take lots of time studying, it's possible to lead them to Christ by pointing that out. The problem is convincing them our Bible scriptures are the same as when Muhammad lived (7th century). There's plenty of evidence the Bible hasn't changed, so if you can show that, you have a chance. From there we can then lead them to those pre-7th century scriptures the Quran claims it honors.
Then some real challenges arise, like showing proof of Jesus being of the godhead bodily, after they have been taught there is no Trinity. Each of them possess a precious soul bought with more price than all the value of the universe, so don't give up a chance to reach them for Jesus.
