Muhammad b. Ahmad al-Sinani al-Mukattib narrated to us. He said: Muhammad b. Abi `Abdillah al-Kufi narrated to us. He said: Sahl b. Ziyad al-Adami narrated to us from `Abd al-`Athim b. `Abdullah al-Hasani from Imam `Ali b. Muhammad from his father Muhammad b. `Ali from his father Al-Rida `Ali b. Musa . He said:

Abu Hanifa departed from al-Sadiq one day and encountered Musa b. Ja`far along the way. So, he said to him: O young man! Who is responsible for the committing of sin? So, he said: There are only three possibilities: (1) It is committed by Allah, which is impossible, because it is not proper for the Merciful to punish His servants for things they have not done. (2) The sin is committed by both Allah and the servant, but it is not proper for a Powerful partner to oppress a weak partner. (3) It is the servant that commits the sin. This is the case. If Allah punishes him, it is due to the sins that he has committed, and if Allah forgives him, it is due to His generosity.
