عَنْ أَبِي مَسْعُودٍ قَالَ أَشَارَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ بِيَدِهِ نَحْوَ الْيَمَنِ فَقَالَ ”الْإِيمَانُ هَاهُنَا الْإِيمَانُ هَاهُنَا وَإِنَّ الْقَسْوَةَ وَغِلَظَ الْقُلُوبِ فِي الْفَدَّادِينَ عِنْدَ أُصُولِ أَذْنَابِ الْإِبِلِ حَيْثُ يَطْلُعُ قَرْنَا الشَّيْطَانِ فِي رَبِيعَةَ وَمُضَرَ“
It is narrated from Sayyiduna Abu Mas'ud Ansari, may Allah be pleased with him, that the Messenger of Allah, peace and blessings be upon him, pointed with his blessed hand towards Yemen and said: "Faith is here, faith is here, and harshness and hardness of hearts are among the owners of camels, from where the horns of Satan will emerge from Rabi'ah and Mudar."
