Maybe strangely, given the general modern attitude about Islam and women, women in this time period might be especially attracted to it, as it has way more respect for women than does the Bible, especially the Old Testament...
I suspect that this could be the case, but the stuff that contravened Christian sexual taboos (particularly polygamy and divorce) may have alienated a literate Christian audience.
For protestants the text of the bible became vitally important, and that text has been arranged into a narrative, while the Koran hasn't.
Islam tends to be exported wholesale as a life-style, and in that sense it is a very powerful meme, but the Koran on its own is a tough sell to an already literate population, unless it goes hand in hand with political control.
