The Prophet ﷺ said: There will be civil strife (fitnah) which will render people deaf, dumb and blind regarding what is right. Those who contemplate it will be drawn by it, and giving rein to the tongue during it will be like smiting with the sword.  

أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ سَتَكُونُ فِتْنَةٌ صَمَّاءُ بَكْمَاءُ عَمْيَاءُ مَنْ أَشْرَفَ لَهَا اسْتَشْرَفَتْ لَهُ وَإِشْرَافُ اللِّسَانِ فِيهَا كَوُقُوعِ السَّيْفِ  

The Prophet ﷺ said: There will be civil strife which wipe out the Arabs, and their slain will go to Hell. During it the tongue will be more severe than blows of the sword. Abu Dawud said: Al-Thawri transmitted it from Laith, from Tawus on the authority of Al-A'jam.  

قَالَ رَسُولُ اللَّهِ ﷺ إِنَّهَا سَتَكُونُ فِتْنَةٌ تَسْتَنْظِفُ الْعَرَبَ قَتْلاَهَا فِي النَّارِ اللِّسَانُ فِيهَا أَشَدُّ مِنْ وَقْعِ السَّيْفِ  

Ziyad, one who has white ears.  

زِيَادٌ سِيمِينْ كُوشْ
