Sahih al-Bukhari 1522
Narrated Zaid bin Jubair:
I went to visit `Abdullah bin `Umar at his house which contained many tents made of cotton cloth and 
these were encircled with Suradik (part of the tent). I asked him from where, should one assume Ihram 
for Umra. He said, "Allah's Messenger (ﷺ) had fixed as Miqat (singular of Mawaqit) Qarn for the people of 
Najd, Dhul-Hulaifa for the people of Medina, and Al-Juhfa for the people of Sham."
حَدَّثَنَا مَالِكُ بْنُ إِسْمَاعِيلَ، حَدَّثَنَا زُهَيْرٌ، قَالَ حَدَّثَنِي زَيْدُ بْنُ جُبَيْرٍ، أَنَّهُ أَتَى عَبْدَ اللَّهِ بْنَ عُمَرَ ـ رضى الله عنهما ـ فِي مَنْزِلِهِ وَلَهُ فُسْطَاطٌ وَسُرَادِقٌ، فَسَأَلْتُهُ مِنْ أَيْنَ يَجُوزُ أَنْ أَعْتَمِرَ قَالَ فَرَضَهَا رَسُولُ اللَّهِ صلى الله عليه وسلم لأَهْلِ نَجْدٍ قَرْنًا، وَلأَهْلِ الْمَدِينَةِ ذَا الْحُلَيْفَةِ، وَلأَهْلِ الشَّأْمِ الْجُحْفَةَ‏.‏
