10-1 Ali ibn Abdillah al-Warraq - may God be pleased with him - narrated that Sa’d ibn Abdillah quoted on the authority of Ahmad ibn Abi Abdillah al-Barqi, on the authority of his father, on the authority of Rabi ibn Abdurrahman, “I swear by God that Musa ibn Ja’far صلى الله عليه وعلى آله وسلم was extremely intelligent. He knew those who will stop believing in Divine Leadership after him, and not accept the next Divine Leaders. However, he صلى الله عليه وعلى آله وسلم quenched his anger and did not divulge what he صلى الله عليه وعلى آله وسلم knew about them. That is why he صلى الله عليه وعلى آله وسلم is called ’Kadhim.“
