Musnad Ahmad 33:250

Abu Mu'awiyah 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) said during his Hajj: "Which day is the greatest in sanctity?" They said: "This day of ours." He said: "Then which month is the greatest in sanctity?" They said: "This month of ours." He said: "Then which land is the greatest in sanctity?" They said: "This land of ours." He said: "For indeed, your blood and your wealth are sacred to you, like the sanctity of this day of yours, in this month of yours, in this land of yours."
