The Messenger of Allah (SWAS) appointed the following places for putting on Ihram : Dhul al-Hulaifah for the people of Madina, al-Juhfah for the people of Syria and al-Qarn for the people of Najd and have been told that appointed Yalamlam for the people of Yemen. (Using translation from Abū Dāʾūd 1737)   

«وَقَّتَ رَسُولُ اللَّهِ ﷺ لِأَهْلِ الْمَدِينَةِ ذَا الْحُلَيْفَةِ وَلِأَهْلِ الشَّامِ الْجُحْفَةَ وَلِأَهْلِ نَجْدٍ قَرْنًا» قَالَ قَالَ ابْنُ عُمَرَ أَمَّا هَذِهِ الثَّلَاثُ فَإِنِّي سَمِعْتُهُنَّ مِنْ رَسُولِ اللَّهِ ﷺ وَبَلَغَنِي «أَنَّهُ وَقَّتَ لِأَهْلِ الْيَمَنِ يَلَمْلَمَ»  

[Machine] "Like him is Ibn Umar."  

عَنْ ابْنِ عُمَرَ مِثْلَهُ  

Messenger of Allah ﷺ made Dhul-Huiaifa as the Miqat for the people of Medina; Al-Juhfa for the people of Sham; Qarn-al-Manazil for the people of Najd; and Yalamlam for the people of Yemen; and these Mawaqit are for the people at those very places, and besides them for those who come thorough those places with the intention of performing Hajj and ʿUmra; and whoever is living within these boundaries can assume lhram from the place he starts, and the people of Mecca can assume Ihram from Mecca. (Using translation from Bukhārī 1524)  

«أَنَّ النَّبِيَّ ﷺ وَقَّتَ لِأَهْلِ الْمَدِينَةِ ذَا الْحُلَيْفَةِ وَلِأَهْلِ الشَّامِ الْجُحْفَةَ وَلِأَهْلِ نَجْدٍ قَرْنَ الْمَنَازِلِ وَلِأَهْلِ الْيَمَنِ يَلَمْلَمَ هُنَّ لِأَهْلِهِنَّ وَلِكُلِّ آتٍ أَتَى عَلَيْهِنَّ مِنْ غَيْرِهِنَّ مِمَّنْ أَرَادَ الْحَجَّ وَالْعُمْرَةَ وَمَنْ كَانَ دُونَ ذَلِكَ فَمِنْ حَيْثُ أَنْشَأَ حَتَّى أَهْلُ مَكَّةَ مِنْ مَكَّةَ»
