Salim b. 'Abdullah b. 'Umar b. al-Khattab (Allah be pleased with them) reported his father as saying: I heard the Messenger of Allah as saying that the people of Medina should enter upon the state of Ihram at Dhu'l- Hulaifa, the people of Syria at Mahya'a and that is Juhfa, and the people of Najd at Qarn (al-Manazil). 'Abdullah b.

وَحَدَّثَنِي حَرْمَلَةُ بْنُ يَحْيَى، أَخْبَرَنَا ابْنُ وَهْبٍ، أَخْبَرَنِي يُونُسُ، عَنِ ابْنِ شِهَابٍ، عَنْ سَالِمِ بْنِ عَبْدِ اللَّهِ بْنِ عُمَرَ بْنِ الْخَطَّابِ، - رضى الله عنه - عَنْ أَبِيهِ، قَالَ سَمِعْتُ رَسُولَ اللَّهِ صلى الله عليه وسلم يَقُولُ ‏"‏ مُهَلُّ أَهْلِ الْمَدِينَةِ ذُو الْحُلَيْفَةِ وَمُهَلُّ أَهْلِ الشَّامِ مَهْيَعَةُ وَهِيَ الْجُحْفَةُ وَمُهَلُّ أَهْلِ نَجْدٍ قَرْنٌ ‏"‏ ‏.‏ قَالَ عَبْدُ اللَّهِ بْنُ عُمَرَ - رضى الله عنهما - وَزَعَمُوا أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم - وَلَمْ أَسْمَعْ ذَلِكَ مِنْهُ - قَالَ ‏"‏ وَمُهَلُّ أَهْلِ الْيَمَنِ يَلَمْلَمُ ‏"‏ ‏.‏
