Musnad Ahmad 33:873

Muhammad ibn Ubayd narrated to us, al-A’mash narrated to us, from Abu Salih, from Jabir, who said: The Messenger of Allah (peace and blessings of Allah be upon him) delivered a sermon to us on the Day of Sacrifice (Yawm al-Nahr) and said: "Which day is the greatest in sanctity?" They said: "This day of ours." He said: "Which month is the greatest in sanctity?" They said: "This month of ours." He said: "Which land is the greatest in sanctity?" They said: "This land of ours." He said: "Indeed, your blood and your wealth are sacred to you, like the sanctity of this day of yours, in this land of yours, in this month of yours. Have I conveyed [the message]?" They said: "Yes." He said: "O Allah, bear witness."
