Sayyiduna Abdur Rahman bin Abu Bakrah (may Allah be pleased with him) narrates that the Messenger of Allah (peace and blessings be upon him) delivered a sermon to us on the Day of Sacrifice (the 10th of Dhul-Hijjah) and said: "What day is this?" We said: Allah and His Messenger know best. He remained silent until we thought he would give it another name. Then he asked: "Is it not the Day of Sacrifice?" We said: Yes! He asked: "What month is this?" We said: Allah and His Messenger know best. He remained silent until we thought he would give it another name. Then he asked: "Is it not Dhul-Hijjah?" We said: Yes! He asked: "What city is this?" We said: Allah and His Messenger know best. He remained silent until we thought he would give it another name. Then he asked: "Is it not (the sacred city of) Makkah?" We said: Yes! The Messenger of Allah (peace and blessings be upon him) said: "Indeed, Allah has made your blood and your wealth sacred to you, just as this day of yours, this month of yours, and this city of yours are sacred, and this sanctity remains until the Day of Resurrection. Have I conveyed (the message of Allah)?" The noble Companions (may Allah be pleased with them) said: Yes! He said: "O Allah! Bear witness. Let those present convey this message to those who are absent, for sometimes the one to whom the message is conveyed remembers it better than the one who heard it. Beware! Do not turn back to disbelief after me, striking the necks of one another."
