وَحَدَّثَنَا يَحْيَى بْنُ يَحْيَى، قَالَ قَرَأْتُ عَلَى مَالِكٍ عَنْ نَافِعٍ، عَنِ ابْنِ عُمَرَ، - رضى الله عنهما - أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم قَالَ ‏"‏ يُهِلُّ أَهْلُ الْمَدِينَةِ مِنْ ذِي الْحُلَيْفَةِ وَأَهْلُ الشَّامِ مِنَ الْجُحْفَةِ وَأَهْلُ نَجْدٍ مِنْ قَرْنٍ ‏"‏ ‏.‏ قَالَ عَبْدُ اللَّهِ وَبَلَغَنِي أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم قَالَ ‏"‏ وَيُهِلُّ أَهْلُ الْيَمَنِ مِنْ يَلَمْلَمَ ‏"‏ ‏.‏
