(18) Yazeed bin Sinan and Uthman bin Abu Shayba narrated from Musa bin Issma’eel from Hammad bin Salama from Sammak bin Harb that Jabir bin Samra had said: I heard the Prophet (S) saying: “Islam will still be strong until twelve caliphs (pass away).” Then he said something that I could not understand. I asked my father what the Prophet (S) had said. He said to me: “He said: All of them are from Quraysh.”
