It was narrated that Ibn 'Abbas (رضي الله عنه) said:

The Messenger of Allah (ﷺ) defined the meeqat of the people of Madinah as Dhul-Hulaifah; that of the people of Sham (Syria) as al-Juhfah; that of the people of Yemen as Yalamlam; and that of the people of Najd as Qarn. And he said: "And these meeqats are for the people at those very places, and besides them for those who come through those places with the intention of performing Hajj and ‘Umrah; and whoever is living within these boundaries can enter ihram from the place he sets out, and so on, and the people of Makkah can enter ihram from where they start.
