Sayyiduna Abdullah bin Umar (may Allah be pleased with them both) narrates that the Messenger of Allah (peace and blessings be upon him) fixed Dhu’l-Hulaifa as the miqat for the people of Madinah, Juhfa for the people of Sham, Qarn for the people of Najd, and I have not heard (directly), but I have been informed that he fixed Yalamlam as the miqat for the people of Yemen.
