وَعَنْ أَبِي مَسْعُودٍ الْأَنْصَارِيِّ عَنِ النَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ قَالَ: «مِنْ هَهُنَا جَاءَتِ الْفِتَنُ - نَحْوَ الْمَشْرِقِ - وَالْجَفَاءُ وَغِلَظُ الْقُلُوبِ فِي الْفَدَّادِينَ أَهْلِ الْوَبَرِ عِنْدَ أُصُولِ أَذْنَابِ الْإِبِلِ وَالْبَقَرِ فِي رَبِيعَةَ وَمُضَرَ» . مُتَّفَقٌ عَلَيْهِ
