Musnad Abu Ya'la al-Mawsili 153:61

'Amr al-Naqid narrated to us, Sufyan narrated to us, from al-Zuhri, from Salim, from his father, from the Prophet (peace be upon him), who said: "The people of Medina shall enter into Ihram from Dhu al-Hulayfah, the people of al-Sham from al-Juhfah, and the people of Najd from Qarn." He said: "And it was mentioned to me—though I did not hear it [from the Prophet]—that he said: 'And the people of Yemen shall enter into Ihram from Yalamlam.'"
