حَدَّثَنَا قُتَيْبَةُ بْنُ سَعِيدٍ، حَدَّثَنَا لَيْثٌ، ح وَحَدَّثَنِي مُحَمَّدُ بْنُ رُمْحٍ، أَخْبَرَنَا اللَّيْثُ، عَنْ نَافِعٍ، عَنِ ابْنِ عُمَرَ، أَنَّهُ سَمِعَ رَسُولَ اللَّهِ صلى الله عليه وسلم وَهُوَ مُسْتَقْبِلُ الْمَشْرِقِ يَقُولُ ‏"‏ أَلاَ إِنَّ الْفِتْنَةَ هَا هُنَا أَلاَ إِنَّ الْفِتْنَةَ هَا هُنَا مِنْ حَيْثُ يَطْلُعُ قَرْنُ الشَّيْطَانِ ‏"‏ ‏.‏
Translation
Salim b. Abdullah reported on the authority of his father that Allah's Messenger (ﷺ), while turning his face towards the east, said

The turmoil would appear from this side; verily, the turmoil would appear from this side; verily, the turmoil would appear from this side - the side where appear the horns of Satan.
