It is narrated from Sayyiduna Ibn Umar (may Allah be pleased with them both) that the Prophet (peace and blessings be upon him) fixed Dhu’l-Hulayfah as the miqat for the people of Madinah, Juhfah for the people of Sham, Qarn for the people of Najd. I have been informed that the Prophet (peace and blessings be upon him) fixed Yalamlam as the miqat for the people of Yemen.
