Sayyidah Aishah (may Allah be pleased with her) said that the Messenger of Allah (peace and blessings be upon him) said: "The people of Madinah will say the talbiyah from Dhu al-Hulayfah, the people of Sham and Egypt from al-Juhfah, the people of Yemen from Yalamlam, and for the people of Iraq it is Dhat Irq."
