حَدَّثَنَا أَبُو بَكْرِ بْنُ أَبِي شَيْبَةَ، وَأَبُو كُرَيْبٍ قَالاَ حَدَّثَنَا أَبُو مُعَاوِيَةَ، عَنِ الأَعْمَشِ، عَنْ أَبِي صَالِحٍ، عَنْ أَبِي هُرَيْرَةَ، قَالَ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم ‏"‏ أَتَاكُمْ أَهْلُ الْيَمَنِ هُمْ أَلْيَنُ قُلُوبًا وَأَرَقُّ أَفْئِدَةً الإِيمَانُ يَمَانٍ وَالْحِكْمَةُ يَمَانِيَةٌ رَأْسُ الْكُفْرِ قِبَلَ الْمَشْرِقِ ‏"‏ ‏.‏
