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 heard Messenger of Allah ﷺ while he was facing the East, saying, "Verily! Afflictions are there, from where the side of the head of Satan comes out."  

أَنَّهُ سَمِعَ رَسُولَ اللَّهِ ﷺ وَهْوَ مُسْتَقْبِلٌ الْمَشْرِقَ يَقُولُ أَلاَ إِنَّ الْفِتْنَةَ هَا هُنَا مِنْ حَيْثُ يَطْلُعُ قَرْنُ الشَّيْطَانِ  

The Prophet ﷺ said, "O Allah! Bestow Your blessings on our Sham! O Allah! Bestow Your blessings on our Yemen." The People said, "And also on our Najd." He said, "O Allah! Bestow Your blessings on our Sham (north)! O Allah! Bestow Your blessings on our Yemen." The people said, "O Allah's Apostle! And also on our Najd." I think the third time the Prophet ﷺ said, "There (in Najd) is the place of earthquakes and afflictions and from there comes out the side of the head of Satan."  

ذَكَرَ النَّبِيُّ ﷺ اللَّهُمَّ بَارِكْ لَنَا فِي شَأْمِنَا اللَّهُمَّ بَارِكْ لَنَا فِي يَمَنِنَا قَالُوا وَفِي نَجْدِنَا قَالَ اللَّهُمَّ بَارِكْ لَنَا فِي شَأْمِنَا اللَّهُمَّ بَارِكْ لَنَا فِي يَمَنِنَا قَالُوا يَا رَسُولَ اللَّهِ وَفِي نَجْدِنَا فَأَظُنُّهُ قَالَ فِي الثَّالِثَةَ هُنَاكَ الزَّلاَزِلُ وَالْفِتَنُ وَبِهَا يَطْلُعُ قَرْنُ الشَّيْطَانِ  

ʿAbdullah bin ʿUmar came to us and we hoped that he would narrate to us a good Hadith. But before we asked him, a man got up and said to him, "O Abu ʿAbdur-Rahman! Narrate to us about the battles during the time of the afflictions, as Allah says:-- 'And fight them until there is no more afflictions (i.e. no more worshipping of others besides Allah).'" (2.193) Ibn ʿUmar said (to the man), "Do you know what is meant by afflictions? Let your mother bereave you! Muhammad used to fight against the pagans, for a Muslim was put to trial in his religion (The pagans will either kill him or chain him as a captive). His fighting was not like your fighting which is carried on for the sake of ruling."  

حَدِّثْنَا عَنِ الْقِتَالِ فِي الْفِتْنَةِ وَاللَّهُ يَقُولُ {وَقَاتِلُوهُمْ حَتَّى لاَ تَكُونَ فِتْنَةٌ} فَقَالَ هَلْ تَدْرِي مَا الْفِتْنَةُ ثَكِلَتْكَ أُمُّكَ إِنَّمَا كَانَ مُحَمَّدٌ ﷺ يُقَاتِلُ الْمُشْرِكِينَ وَكَانَ الدُّخُولُ فِي دِينِهِمْ فِتْنَةً وَلَيْسَ كَقِتَالِكُمْ عَلَى الْمُلْكِ
