I heard Messenger of Allah ﷺ as saying while pointing his hands towards the east: The turmoil would appear from this side; verily, the turmoil would appear from this side (he repeated it thrice) where appear the horns of Satan. (Using translation from Muslim 2905e)
رَأَيْتُ رَسُولَ اللهِ ﷺ يُشِيرُ بِيَدِهِ يَؤُمُّ الْعِرَاقَ هَا إِنَّ الْفِتْنَةَ هَاهُنَا هَا إِنَّ الْفِتْنَةَ هَاهُنَا ثَلَاثَ مَرَّاتٍمِنْ حَيْثُ يَطْلُعُ قَرْنُ الشَّيْطَانِ
