Musnad Ahmad

It is narrated from Hazrat Nabi T (may Allah be pleased with him) that on the occasion of the Farewell Pilgrimage, I was sitting behind my father on the mount. When the Prophet Muhammad (peace and blessings be upon him) began the sermon, I stood on the rear part of the mount and placed my hand on my father's shoulder. I heard the Prophet Muhammad (peace and blessings be upon him) saying: "Which day is the most sacred?" The companions (may Allah be pleased with them) replied, "Today." The Prophet (peace and blessings be upon him) asked, "Which city is the most sacred?" The companions replied, "This city (Makkah)." Then he asked, "Which month is the most sacred?" The companions (may Allah be pleased with them) replied, "The present month." The Prophet Muhammad (peace and blessings be upon him) said, "Then your lives and your wealth are as sacred and inviolable to each other as the sanctity of this day, in this month, in this city. Have I conveyed the message to you?" The companions (may Allah be pleased with them) replied, "Yes!" The Prophet Muhammad (peace and blessings be upon him) said, "O Allah! Bear witness. O Allah! Bear witness."
