Narrated Abi Mas`ud:
حَدَّثَنَا عَلِيُّ بْنُ عَبْدِ اللَّهِ ، حَدَّثَنَا سُفْيَانُ ، عَنْ إِسْمَاعِيلَ ، عَنْ قَيْسٍ ، عَنْ أَبِي مَسْعُودٍ ، يَبْلُغُ بِهِ النَّبِيَّ صلى الله عليه وسلم قَالَ " مِنْ هَا هُنَا جَاءَتِ الْفِتَنُ نَحْوَ الْمَشْرِقِ، وَالْجَفَاءُ وَغِلَظُ الْقُلُوبِ فِي الْفَدَّادِينَ أَهْلِ الْوَبَرِ عِنْدَ أُصُولِ أَذْنَابِ الإِبِلِ، وَالْبَقَرِ فِي رَبِيعَةَ وَمُضَرَ " .
The Prophet (ﷺ) said, "From this side from the east, afflictions will appear. Rudeness and lack of mercy are characteristics of the rural bedouins who are busy with their camels and cows (and pay no attention to religion). Such are the tribes of Rabi`a and Mudar."
