Allah's Messenger (ﷺ) had fixed Dhul Hulaifa as the Miqat for the people of Medina; Al-Juhfa for the people
of Sham; and Qarn Ul-Manazil for the people of Najd; and Yalamlam for the people of Yemen. So,
these (above mentioned) are the Mawaqit for all those living at those places, and besides them for
those who come through those places with the intention of performing Hajj and `Umra and whoever
lives within these places should assume Ihram from his dwelling place, and similarly the people of
Mecca can assume lhram from Mecca.
Sahih al-Bukhari Book 25, Hadith 14
