As far as I can recall, the study time, the recreation time and working time of the Imam were separate because the Imam was basically a disciplined person and exercised discipline in all his tasks. Naturally, he was disciplined even in his reading habits. I remember from the time of childhood that he was fond of reading. From the time we would awaken in the morning, we would see him awake and my mother would say that after reciting prayers, he would not go back to sleep.[1]
