12-20 Ahmad ibn al-Hassan al-Qat’tan narrated that Abdul Rahman ibn Abi Hatam quoted Al-Ala’ ibn Salim, on the authority of Yazid ibn Harun, on the authority of Sharik, on the authority of Samak, Abdullah ibn Umayr and Haseen ibn Abdul Rahman, on the authority of Jabir ibn Samurah,

“My father and I went to see God’s Prophet (MGB). The Prophet (MGB) said, ‘The rule of this good nation will not terminate and it shall overcome its enemies until there come twelve rulers after me.’ Or he (MGB) said, ‘… until there come twelve Caliphs after me.’ Then the Prophet (MGB) said something quietly. I asked my father, ‘What did he (MGB) say?’ My father said, ‘The Prophet (MGB) said, ‘They are all from the Quraysh.’”
