Sayyiduna Abdullah bin Abbas (may Allah be pleased with them both) said that the Messenger of Allah (peace and blessings be upon him) appointed Dhu al-Hulayfah as the miqat for the people of Madinah, al-Juhfah for the people of Sham, Qarn al-Manazil for the people of Najd, and Yalamlam for the people of Yemen: "These are for them, and for those who pass by them even if they are from another region, who intend Hajj and Umrah. Whoever lives within them, on the side of Makkah, should enter ihram and say the talbiyah from his home, so much so that the people of Makkah will say the talbiyah from Makkah itself."
