Al-Adab Al-Mufrad, Book 30, Hadith 37 (In-Book) ⓘ

Abu Hurayra reported that the Messenger of Allah, may Allah bless him and grant him peace, said, "The head (or summit) of disbelief lies towards the east and the pride and arrogance lie in people who possess horses and camels who are also coarse - the bedouins. Tranquillity lies in people who possess sheep."

حَدَّثَنَا إِسْمَاعِيلُ قَالَ‏:‏ حَدَّثَنِي مَالِكٌ، عَنْ أَبِي الزِّنَادِ، عَنِ الأَعْرَجِ، عَنْ أَبِي هُرَيْرَةَ، أَنَّ رَسُولَ اللهِ صلى الله عليه وسلم قَالَ‏:‏ رَأْسُ الْكُفْرِ نَحْوَ الْمَشْرِقِ، وَالْفَخْرُ وَالْخُيَلاَءُ فِي أَهْلِ الْخَيْلِ وَالإِبِلِ، الْفَدَّادِينَ أَهْلِ الْوَبَرِ، وَالسَّكِينَةُ فِي أَهْلِ الْغَنَمِ‏.‏
