abu al-Hassan al-Rida (a.s.), said to me the following: “O Yunus do not say what pre-determinists say. The pre- determinists do not say what people of paradise say or what people of hell say or what Satan says. The people of paradise say, ‘. . . all praise is due to Allah for His guiding us. We could never have been guided without Allah’s guiding us.’ (7:43) The people of hell say, ‘Lord, our misfortune overwhelmed us and we became lost,’ (23:107) and Satan said, ‘My Lord for your making me to rebel . . .’ (15:39) “I then said, ‘I swear by Allah that I do not say what they say but I only say that there will be nothing unless Allah will want, will, measure and decree.’ The Imam (a.s.), said, ‘O Yunus, it is not that, ‘there will be nothing unless Allah will want, will, measure and decree.’ O Yunus, do you know what is want?’ I said, ‘No, I do not know.’ The Imam said, ‘It is the first mention of something. Do you know what is will?’ I said, ‘No, I do not know.’ The Imam said, ‘It is the intention to do something. Do you know what measurement is?’ I said, ‘No, I do not know.’ The Imam said, ‘It is the figure, the position, the limits of survival and extinction.’ “The Imam further said, ‘The decree is the readiness and the production of substance.’ I then asked permission to kiss his head and said, ‘You just opened for me something of which I was unaware.’”
