  At 11 a.m.  sudden changes were examined in Imam's heart beating which became a source of  concern for the doctors. I personally conveyed Sayyid Ahmad, the son of Imam,  that the current physical condition of Imam is very worrying. 
  Haj Ahmad was recommended to spare all of his time to  attend Imam so he can share discussions with Imam during these precious  moments. These moments should not be lost at any cost. This stable but  unsatisfactory physical situation continued for some coming hours. 
  The blood pressure was very low and being monitored for  each moment. The blood pressure was even gradually dropping by passing of each  moment. However, Imam was in a complete conscious condition. Then Imam said his  noon prayers and around 15 p.m. he experienced a sudden heart attack and halt.  He was assisted with oxygen masks to regulate his breathing system and  normalize heart beating.  
  At this point Imam had slipped into a coma but could  claim his consciousness after some hours. He showed some movements but the  condition was disappointing. This state continued for some more hours. When the  clock was ticking at 10: 23 p.m. the blood pressure had reached to its lowest  level and spiritual heart of dear Imam stopped working.

A Narrative about the Mystic Person
  One day I visited Imam and he described a narrative  of a mystic man and said: 
  "A few days were left from the life of an old mystic  man.  He went to loneliness after jumping  to the conclusion that he had thrown away all material associations. He was now  getting ready for spiritual departure towards God the Almighty. However, he had  a small child at home and loved him very much. Then he felt even his love  towards this small lovely child was hindering him to absolute truth…"
  I knew that Imam had never uttered a single world without  spiritual purpose. By the passage of time Imam's physical conditions turned  fragile. The doctors had advised us to engage Imam in talks and this can  improve his health condition. I visited Imam and insisted that I will bring  little Ali. Imam replied let the child feel comfort and feel easy. Imam did not  show too much devotion to see Ali in these circumstances. However, I picked Ali  and brought him to the hospital in order to provide a change and company for  Imam. He did not kissed little Ali but his eyes were filled with tears. This is  while the great Imam always used to search for Ali and kissed him several  times. Actually Imam had become aware of his death and he wanted to get rid of  any kind of associations of this world during last days of his life.

These are Final Days
  Nearly two weeks before Imam undergo for a  surgery, I went to Imam along with two doctors and two nurses to provide the  premises for his hospitalization. They hospitalized and started his treatment.  When they were scaling and checking blood pressure, Imam said the "the  mission accomplished and job is over." I said God willing you will recover  soon and live a longer life. The great Imam repeated the same expression. When  we were returning from the hospital, one of the nurses started shedding tears.  The nurse said Imam was predicting his last days of life through uttering these  expressions. However, one of the doctors justified by saying that Imam meant he  will be healed and recovers soon. Imam had expressed the same expression even  some days before this incident. Actually he was mentally preparing us about his  death.
