It is reporter on the authority of Abu Huraira that the Messenger of Allah (may peace and blessings be upon him) observed:There came the people of Yemen who are soft of hearts, tender in feelings: the belief is that of the Yemenites, the sagacity is that of the Yemenites and the summit of unbelief is towards the East.
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 " .
