Sayyiduna Jabir bin Samurah (may Allah be pleased with him) narrates: I heard the Prophet Muhammad (peace and blessings be upon him) say: "Islam will remain dominant until twelve caliphs." The narrator says: Then the Prophet Muhammad (peace and blessings be upon him) said something which I did not understand. I asked my father: What did the Prophet Muhammad (peace and blessings be upon him) say? He replied (the Prophet Muhammad (peace and blessings be upon him) said): All of these caliphs will be from the Quraysh."
