Muhammad ibn abu ‘Abd Allah has narrated from Sahl ibn Ziyad and Ali ibn Ibrahim has narrated from Ahmad ibn Muhammad and Muhammad ibn Yahya from Ahmad ibn Muhammad all from Ali ibn al-Hakam from Salih al-Nily who said the following: “Once I asked abu ‘Abd Allah عليه السلام, ‘Do the servants (of Allah) have any capability?’ The Imam said, ‘When they act an act they do have the capability that Allah has placed in them.’ I asked, ‘What is it?’ The Imam said, ‘It is a means. In a sin like adultery when one commits such sins he has the capability when he is in such an act. If he however, desists from such an act he has the capability to refrain.’ The Imam further said, ‘Before the act he does not have the capability in a small or large measure but at the time of the act or desisting, he has the capability.’ “I asked, ‘What for then are they punished?’ The Imam said, ‘It is because of complete justification and because of the means that are placed in them. Allah does not compel anyone into sins. Also He does not will, in a definite form of will, disbelief for anyone, but when one disbelieves it is in the will of Allah for him to disbelieve and it is in the will and knowledge of Allah that he will not turn into anything good.’ “I asked, ‘Has He willed disbelief for them?’ The Imam said, ‘It is not quite like that but I say that Allah knew that they would disbelieve, thus He has willed it for them because of His knowledge of it. It is not a definite will. It is a will of choice.’”
