Sahih Bukhari Volume 2, Book 25, Hadith 1530

حَدَّثَنَا قُتَيْبَةُ، حَدَّثَنَا حَمَّادٌ، عَنْ عَمْرٍو، عَنْ طَاوُسٍ، عَنِ ابْنِ عَبَّاسٍ ـ رضى الله عنهما ـ أَنَّ النَّبِيَّ صلى الله عليه وسلم وَقَّتَ لأَهْلِ الْمَدِينَةِ ذَا الْحُلَيْفَةِ، وَلأَهْلِ الشَّأْمِ الْجُحْفَةَ، وَلأَهْلِ الْيَمَنِ يَلَمْلَمَ، وَلأَهْلِ نَجْدٍ قَرْنًا، فَهُنَّ لَهُنَّ وَلِمَنْ أَتَى عَلَيْهِنَّ مِنْ غَيْرِ أَهْلِهِنَّ، مِمَّنْ كَانَ يُرِيدُ الْحَجَّ وَالْعُمْرَةَ فَمَنْ كَانَ دُونَهُنَّ فَمِنْ أَهْلِهِ حَتَّى إِنَّ أَهْلَ مَكَّةَ يُهِلُّونَ مِنْهَا‏

Narrated By Ibn Abbas : The Prophet fixed Dhul-Hulaifa as the Miqat for the people of Medina, Al-Juhfa, for the people of Sham, Yalamlam for the people of Yemen, and Qarn for the people of Najd. And these Mawaqlt are for those living at those very places, and besides them for those who come through those places with the intention of performing Hajj and Umra; and whoever is living inside these places can assume Ihram from his own dwelling place, and the people of Mecca can assume Ihram from Mecca.
