(15) باب خَيْرُ مَالِ الْمُسْلِمِ غَنَمٌ يَتْبَعُ بِهَا شَعَفَ الْجِبَالِ
Narrated Abu Huraira:
Allah's Messenger (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."
