It has been recalled through a series of memoirs that Imam always remembered God Almighty when he was hospitalized.
Doctors and people within close circle of Imam say that he was frequently asking about the timing of prayers during his sickness period.
Illness or any pain couldn’t detach him from reciting the holy Quran and supplications or remembrance of Allah
A memoirs mentions that Imam Khomeini had kept remembering God the Almighty amid air in the airplane while making a historic return to his homeland nearly spending 15 years in exile.
Mohammad Sadiq Tabataba’ei, who accompanied Imam during his historic return from Paris to Tehran in 1979, said that Imam had never forgot remembrance of God even for a moment in all thick and thin conditions.
Despite all hurdles and challenges Imam was facing at the time, he continued saying his prayers and supplication at the Air France airplane which was carrying imam towards Tehran. Imam had not missed his mid-night and morning prayers at the plane.
They were all deeply impressed by Imam’s ethical norms as he used to welcome them warmly and always thanked for their attention.
