Re: Steeped in ancient mysticism, passion of Pakistani Sufis infuriates Taliban
No, you should come up with those hadith … but then, I have read large part of Sahi Bukhari, Sahi Muslim, and Muwatta, and also lot of other hadith books … but never came with any hadith ‘linking Horn of Shaitan with Iraq’ … so if you quote the hadith you are claiming with reference than it would be great thing for my knowledge (and knowledge of all who would read you). 
As far as I know, the only hadith some misguided people claim linking ‘Iraq with horn of Shaitan’ is the one I quoted in my earlier post … and along with my quote I also gave explanation why what they claim is absurd.
