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
