I went to visit ʿAbdullah bin ʿUmar 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, "Messenger of Allah 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."  

فَرَضَهَا رَسُولُ اللَّهِ ﷺ لأَهْلِ نَجْدٍ قَرْنًا وَلأَهْلِ الْمَدِينَةِ ذَا الْحُلَيْفَةِ وَلأَهْلِ الشَّأْمِ الْجُحْفَةَ
