Sahih Muslim 1182 c
Salim b. 'Abdullah b. 'Umar b. al-Khattab (Allah be pleased with them) reported his father as saying:
I heard the Messenger of Allah (ﷺ) 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. 'Umar (Allah be pleased with them) said: (I did not hear it myself from him) but heard from them saying that the Messenger of Allah (ﷺ) had (also) said: The people of Yemen should enter upon the state of Ihram at Yalamlam.
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 ‏"‏ ‏.‏
