Ibn 'Umar reported that he heard Allah's Messenger (ﷺ) as saying (in a state) that he had turned his face towards the east:Behold, turmoil would appear from this side, from where the horns of Satan would appear.
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 " .
