باب مَوَاقِيتِ الْحَجِّ وَالْعُمْرَةِ ‏
Sahih Muslim 1182 a

Ibn 'Umar (Allah be pleased with them) reported that the Messenger of Allah (ﷺ) said:

The people of Medina should enter upon the state of Ihram at Dhu'l-Hulaifa, and people of Syria at Juhfa, and people of Najd at Qarn (al-Manazil), and 'Abdullah (further) said: It has reached me that the Messenger of Allah (ﷺ) also caid: The people of Yemen should enter upon the state of Ihram at Yalamlam.
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 ‏"‏ ‏.‏
