Musnad Ahmad 103:0

Narrated by Rafi‘ ibn ‘Amr al-Muzani: The Messenger of Allah (ﷺ) addressed us at Mina, saying: "Do you know what day this is?" We said: "Allah and His Messenger know best." He said: "This is the day of the Great Pilgrimage." Then he said: "Do you know what city this is?" We said: "Allah and His Messenger know best." He said: "This is the Sacred City. Do you know what month this is?" We said: "Allah and His Messenger know best." He said: "This is the Sacred Month." Then he said: "Indeed, your blood, your wealth, and your honor are sacred among you, like the sanctity of this day of yours, in this city of yours, in this month of yours."
