Sahih al-Bukhari 5550

Muḥammad ibn Sallām narrated to us: ʿAbd al-Wahhāb narrated to us: Ayyūb narrated to us, from Muḥammad, from Ibn Abī Bakrah, from Abū Bakrah (may God be pleased with him), from the Prophet ﷺ, who said: “Time has come full circle to its state on the day God created the heavens and the earth. The year has twelve months, four of them sacred: three consecutive months—Dhū al-Qaʿdah, Dhū al-Ḥijjah, and al-Muḥarram—and Rajab of Muḍar, which lies between Jumādā and Shaʿbān.” He said: “Which month is this?” We said, “God and His Messenger know best.” He fell silent until we thought he might call it by a name other than its own. He said: “Is it not Dhū al-Ḥijjah?” We said, “Indeed.” He said: “Which land is this?” We said, “God and His Messenger know best.” He fell silent until we thought he might call it by a name other than its own. He said: “Is it not the town?” We said, “Indeed.” He said: “Which day is this?” We said, “God and His Messenger know best.” He fell silent until we thought he might call it by a name other than its own. He said: “Is it not the Day of Sacrifice?” We said, “Indeed.”

He said: “Your blood, your property”—Muḥammad said, “I think he also said”—“and your honor are sacred to one another, like the sanctity of this day of yours, in this land of yours, in this month of yours. You will meet your Lord, and He will ask you about your deeds. So do not, after me, return as misguided people, striking one another’s necks. Let those present convey this to those absent; perhaps some to whom it is conveyed will understand it better than some who heard it.” Whenever Muḥammad mentioned this, he would say, “The Prophet ﷺ spoke the truth.” Then he said: “Have I conveyed the message? Have I conveyed the message?”
