I could find a prophecy for all religions, but my favorite one for Islam is the following. And with alQuaeda and Daesh (IS), it's come true as I see it:
The time is near in which nothing will remain of Islam but its name, and of the Quran but its mere appearance, and the mosques of Muslims will be destitute of of knowledge and worship; and the learned will be the worst people under the heavens; and contention and strife will issue from them, and it will return upon themselves.
...
Ye follower of Muhammad, I swear by the Lord, if ye did but know what I know of the future state, verily ye would laugh little and cry much.
...
Men will be liars towards the end of the world; and will relate such stories as neither you nor your fathers ever heard. Then avoid them, that they may not lead you astray and throw you into contention and strife.
