Sahih Al Bukhari Hadith Number 1528

Narrated Salim bin `Abdullah from his father: I heard Allah’s Messenger (peace be upon him) saying, “The Miqat for the people of Medina is Dhul-Hulaifa; for the people of Sham is Mahita; (i.e. Al-Juhfa); and for the people of Najd is Qarn. And said Ibn `Umar, “They claim, but I did not hear personally, that the Prophet (peace be upon him) said, “The Miqat for the people of Yemen is Yalamlam.”
