Sahih Muslim 2905 c
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.
وَحَدَّثَنِي حَرْمَلَةُ بْنُ يَحْيَى، أَخْبَرَنَا ابْنُ وَهْبٍ، أَخْبَرَنِي يُونُسُ، عَنِ ابْنِ شِهَابٍ، عَنْ 
 سَالِمِ بْنِ عَبْدِ اللَّهِ، عَنْ أَبِيهِ، أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم قَالَ وَهُوَ مُسْتَقْبِلُ الْمَشْرِقِ
 ‏
"‏ هَا إِنَّ الْفِتْنَةَ هَا هُنَا هَا إِنَّ الْفِتْنَةَ هَا هُنَا هَا إِنَّ الْفِتْنَةَ هَا هُنَا مِنْ حَيْثُ يَطْلُعُ قَرْنُ
 الشَّيْطَانِ ‏"‏ ‏.‏
