The Prophet ﷺ stood up beside the pulpit (and pointed with his finger towards the East) and said, "Afflictions are there! Afflictions are there, from where the side of the head of Satan comes out," or said, "..the side of the sun.."
عَنِ النَّبِيِّ ﷺ أَنَّهُ قَامَ إِلَى جَنْبِ الْمِنْبَرِ فَقَالَ الْفِتْنَةُ هَا هُنَا الْفِتْنَةُ هَا هُنَا مِنْ حَيْثُ يَطْلُعُ قَرْنُ الشَّيْطَانِ أَوْ قَالَ قَرْنُ الشَّمْسِ
I saw Messenger of Allah ﷺ pointing towards the east saying, "Lo! Afflictions will verily emerge hence; afflictions will verily emerge hence where the (side of the head of) Satan appears."
رَأَيْتُ رَسُولَ اللَّهِ ﷺ يُشِيرُ إِلَى الْمَشْرِقِ فَقَالَ هَا إِنَّ الْفِتْنَةَ هَا هُنَا إِنَّ الْفِتْنَةَ هَا هُنَا مِنْ حَيْثُ يَطْلُعُ قَرْنُ الشَّيْطَانِ
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)
أَنَّهُ قَالَ رَأَيْتُ رَسُولَ اللَّهِ ﷺ يُشِيرُ نَحْوَ الْمَشْرِقِ وَيَقُولُ «هَا إِنَّ الْفِتْنَةَ هَاهُنَا إِنَّ الْفِتْنَةَ هَاهُنَا مِنْ حَيْثُ يَطْلُعُ قَرْنُ الشَّيْطَانِ»
