It is narrated from Hazrat Abu Ghadiah Juhani that I pledged allegiance to the Prophet (peace be upon him) on the Day of Aqabah. The Prophet (peace be upon him), addressing us, said: "O people, until the Day of Resurrection, the lives and wealth of people are made unlawful for one another, just as the sanctity of this day in this month and in this city is inviolable. Have I conveyed the message of Allah?" The people affirmed. The Prophet (peace be upon him) said: "O Allah, bear witness. Remember, do not turn into disbelievers after me, striking each other's necks."
