Atheism vs. the Quran

[Rayaan]

This is a variation on the "liar, lunatic or lord" canard that has been offered as "proof" of Christianity.

So what is Muhammad then? A liar or a lunatic? And how do you know this?

And secondly, your picture doesn't relate to Muhammad (pbuh) because never masqueraded as a God. He was only a messenger of God.

To further address the claims of scientific accuracy within the Quran... Embryology in the Quran

Still, there's no good reason to think that Muhammad would plagiarize from Greek writers because (1) he was not able to to read Greek language, (2) there is no report that he went to libraries to find gather all of these scientific information, and (3) why would he lie and fool people into thinking that this is the word of God just to start a whole new religion? I mean, why would he risk his own life by lying? If we assume that he lied, then he would be cursing himself in his own book, and people would've killed him if they found out that he lied. Why? Because there is a verse in the Quran which says:

"Then woe to those who write the Book with their own hands and then say: “This is from Allah” to traffic with it for a miserable price! Woe to them for what their hands do write and for the gain they make thereby." (Surah 2:79)
