Messenger of Allah ﷺ said, "The main source of disbelief is in the east. Pride and arrogance are characteristics of the owners of horses and camels, and those bedouins who are busy with their camels and pay no attention to Religion; while modesty and gentleness are the characteristics of the owners of sheep." (Using translation from Bukhārī 3301)
قَالَ رَسُولُ اللهِ ﷺ رَأْسُ الْكُفْرِ نَحْوَ الْمَشْرِقِ وَالْفَخْرُ وَالْخُيَلَاءُ فِي أَهْلِ الْخَيْلِ وَالْإِبِلِ فِي الْفَدَّادِينَ أَهْلِ الْوَبَرِ وَالسَّكِينَةُ فِي أَهْلِ الْغَنَمِ
