Musnad Ahmad

It is narrated from Hazrat Abu Bakrah (may Allah be pleased with him) that the Prophet (peace and blessings be upon him) rode a camel to deliver a sermon on the occasion of the Farewell Pilgrimage. A man held its rein, then the Prophet (peace and blessings be upon him) said: "Tell me, what day is this?" We replied, "Allah and His Messenger know best." The Prophet (peace and blessings be upon him) remained silent for so long that we thought he might give it another name. But the Prophet (peace and blessings be upon him) said, "Is it not the Day of Sacrifice (Yawm al-Nahr)?" We replied, "Why not." Then he said, "What month is this?" We replied, "Allah and His Messenger know best." The Prophet (peace and blessings be upon him) remained silent for so long that we thought he might give it another name. But the Prophet (peace and blessings be upon him) said, "Is it not the month of Dhu al-Hijjah?" We replied, "Why not." Then he said, "What city is this?" We replied, "Allah and His Messenger know best." The Prophet (peace and blessings be upon him) remained silent as before, then said, "Is it not the Sacred City (Makkah)?" We replied, "Why not." The Prophet (peace and blessings be upon him) said, "Your lives, your wealth, and your honor are as sacred to each other as the sanctity of this day, in this month, in this city. And soon you will meet your Lord, and He will ask you about your deeds. Beware! Do not go astray after me, striking the necks of one another. Have I conveyed the message of Allah?" Let those present convey this message to those who are absent, for sometimes the one to whom the message is conveyed may preserve it better than the one who heard it." The narrator says that it happened just like that.
