Sunan Ibn Majah, Volume 5, Book 36, Hadith 3967 (DarusSalam) ⓘ
It was narrated from ‘Abdullah bin ‘Amr that the Messenger of Allah said: “There will be a tribulation which will utterly destroy the Arabs, and those who are slain will be in Hell. At that time the tongue will be worse than a blow of the sword.”
حَدَّثَنَا عَبْدُ اللَّهِ بْنُ مُعَاوِيَةَ الْجُمَحِيُّ، حَدَّثَنَا حَمَّادُ بْنُ سَلَمَةَ، عَنْ لَيْثٍ، عَنْ طَاوُسٍ، عَنْ زِيَادٍ، سِيمِينْ كُوشْ عَنْ عَبْدِ اللَّهِ بْنِ عَمْرٍو، قَالَ قَالَ رَسُولُ اللَّهِ ـ صلى الله عليه وسلم ـ " تَكُونُ فِتْنَةٌ تَسْتَنْظِفُ الْعَرَبَ قَتْلاَهَا فِي النَّارِ اللِّسَانُ فِيهَا أَشَدُّ مِنْ وَقْعِ السَّيْفِ " .
