3-28 Muhammad ibn al-Hassan ibn Ahmad ibn al-Walid - may God be pleased with him - narrated that Muhammad ibn al-Hassan al-Saffar quoted Al-Ab’bas ibn Maruf, on the authority of Bakr ibn Muhammad, on the authority of Abi Basir that Aba Abdullah as-Sadiq (MGB) said, “There are three roots for infidelity: greed, haughtiness and jealousy. Regarding greed, when Adam was forbidden to eat of the tree, greed caused him to eat of it. Regarding haughtiness, when Satan was ordered to prostrate, he refused to do so. Regarding jealousy, one of the two sons of Adam killed the other one due to jealousy.”
