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 (s) was extremely intelligent. He knew those who will stop believing in Divine Leadership after him, and not accept the next Divine Leaders. However, he (s) quenched his anger and did not divulge what he (s) knew about them. That is why he (s) is called ’Kadhim.“
