It is narrated from Hazrat Jabir bin Samurah (may Allah be pleased with him) that I heard the Prophet (peace and blessings of Allah be upon him) saying during the Farewell Pilgrimage that this religion will always remain dominant; no opponent or anyone who separates from it will be able to harm it, until twelve caliphs have passed in my Ummah. Then the Prophet (peace and blessings of Allah be upon him) said something which I did not understand. I asked my father, "What did the Prophet (peace and blessings of Allah be upon him) say?" He replied that the Prophet (peace and blessings of Allah be upon him) said, "All of them will be from the Quraysh."
