In the last few days of the Imam's life, when he was taken to the hospital, his first recommendation was that he should be told whenever the time of prayers had set in.
During one of those days, a tray of food was brought to his room. Imam asked, "Has the time of prayers set in?" Those present replied, "Yes, it is already the time for prayers." Very sternly, Imam said to those around him, "So why did you not wake me?" They replied, "We were concerned about your health." Imam unhappily said, "Take the food away until I have said my prayers."
