As much as I want the Holy Spirit to change the hearts of Moslems, I would not count them out so quickly. IMHO, Islam are the riders in Revelation 9:16-17
The number of the mounted troops was twice ten thousand times ten thousand. I heard their number.
The horses and riders I saw in my vision looked like this: Their breastplates were fiery red, dark blue, and yellow as sulfur. The heads of the horses resembled the heads of lions, and out of their mouths came fire, smoke and sulfur.
It depends on which Muslims and where — I can see among the 12er Shias (Iran, India) that this is dying out. however among the Sunnis (Saudis, Pakis, etc.) the strain of Wahabbism is spreading fast, thanks to Saudi money and this is getting more fanatical.
