Mishkat al-Masabih 27 Fitan كتاب الفتن 26

وَعَنْ أَبِي هُرَيْرَةَ أَنَّ النَّبِيَّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ قَالَ: «وَيْلٌ لِلْعَرَبِ مِنْ شَرٍّ قَدِ اقْتَرَبَ أَفْلَحَ مَنْ كَفَّ يَدَهُ» . رَوَاهُ أَبُو دَاوُد

Abu Huraira reported the Prophet as saying, “Woe to the Arabs because of evil which has drawn near! He will escape who restrains his hand.” Abu Dawud transmitted it.
