It is narrated on the authority of Ibn Mas'ud that the Messenger of Allah (may peace and blessings be upon him) pointed towards Yemen with his hand and said: Verily Iman is towards this side, and harshness and callousness of the hearts is found amongst the rude owners of the camels who drive them behind their tails (to the direction) where emerge the two horns of Satan, they are the tribes of Rabi'a and Mudar.

حَدَّثَنَا أَبُو بَكْرِ بْنُ أَبِي شَيْبَةَ، حَدَّثَنَا أَبُو أُسَامَةَ، ح وَحَدَّثَنَا ابْنُ نُمَيْرٍ، حَدَّثَنَا أَبِي ح، وَحَدَّثَنَا أَبُو كُرَيْبٍ، حَدَّثَنَا ابْنُ إِدْرِيسَ، كُلُّهُمْ عَنْ إِسْمَاعِيلَ بْنِ أَبِي خَالِدٍ، ح وَحَدَّثَنَا يَحْيَى بْنُ حَبِيبٍ الْحَارِثِيُّ، - وَاللَّفْظُ لَهُ - حَدَّثَنَا مُعْتَمِرٌ، عَنْ إِسْمَاعِيلَ، قَالَ سَمِعْتُ قَيْسًا، يَرْوِي عَنْ أَبِي مَسْعُودٍ، قَالَ أَشَارَ النَّبِيُّ صلى الله عليه وسلم بِيَدِهِ نَحْوَ الْيَمَنِ فَقَالَ ‏ "‏ أَلاَ إِنَّ الإِيمَانَ هَا هُنَا وَإِنَّ الْقَسْوَةَ وَغِلَظَ الْقُلُوبِ فِي الْفَدَّادِينَ عِنْدَ أُصُولِ أَذْنَابِ الإِبِلِ حَيْثُ يَطْلُعُ قَرْنَا الشَّيْطَانِ فِي رَبِيعَةَ وَمُضَرَ ‏"‏ ‏.‏
