Narrated Abu Huraira:
حَدَّثَنَا أَبُو الْيَمَانِ ، أَخْبَرَنَا شُعَيْبٌ ، حَدَّثَنَا أَبُو الزِّنَادِ ، عَنِ الأَعْرَجِ ، عَنْ أَبِي هُرَيْرَةَ ـ رضى الله عنه ـ عَنِ النَّبِيِّ صلى الله عليه وسلم قَالَ " أَتَاكُمْ أَهْلُ الْيَمَنِ، أَضْعَفُ قُلُوبًا وَأَرَقُّ أَفْئِدَةً، الْفِقْهُ يَمَانٍ، وَالْحِكْمَةُ يَمَانِيَةٌ " .
The Prophet (ﷺ) said, "The people of Yemen have come to you, and they are more soft hearted and gentle hearted people. The capacity for understanding religion is Yemenite and Wisdom is Yemenite."
