باب تَفَاضُلِ أَهْلِ الإِيمَانِ فِيهِ وَرُجْحَانِ أَهْلِ الْيَمَنِ فِيهِ ‏
Sahih Muslim 52 h

Abu Huraira said:

I heard the Prophet (may peace and blessings be upon him) saying: There came the people of Yemen, they are tender of feelings and meek of hearts. The belief is that of the Yemenites, the sagacity is that of the Yemenites, the tranquillity is among the owners of goats and sheep, and pride and conceitedness is among the uncivil owners of the camels, the people of the tents in the direction of sunrise.
حَدَّثَنَا عَبْدُ اللَّهِ بْنُ عَبْدِ الرَّحْمَنِ، أَخْبَرَنَا أَبُو الْيَمَانِ، عَنْ شُعَيْبٍ، عَنِ الزُّهْرِيِّ، حَدَّثَنِي سَعِيدُ بْنُ الْمُسَيَّبِ، أَنَّ أَبَا هُرَيْرَةَ، قَالَ سَمِعْتُ النَّبِيَّ صلى الله عليه وسلم يَقُولُ ‏ "‏ جَاءَ أَهْلُ الْيَمَنِ هُمْ أَرَقُّ أَفْئِدَةً وَأَضْعَفُ قُلُوبًا الإِيمَانُ يَمَانٍ وَالْحِكْمَةُ يَمَانِيَةٌ السَّكِينَةُ فِي أَهْلِ الْغَنَمِ وَالْفَخْرُ وَالْخُيَلاَءُ فِي الْفَدَّادِينَ أَهْلِ الْوَبَرِ قِبَلَ مَطْلِعِ الشَّمْسِ ‏"‏ ‏.‏
