It has been recalled through a series of memoirs that the Turkish personnel who had been assigned for security arrangements had been deeply impressed by Imam’s personality during his stay in exile in the city of Bursa.
Once Imam had an academic discussion with his son Mostafa Khomeini and during the seminary- style argument the voice of Mostafa became a bit louder.
At this the security personal thought that a dispute was going on, so they took side of Imam by reminding Mostafa against raising his voice in the presence of such a respectful spiritual figure.
At this, all laughed because the dispute at a very first place had never happened but it was just a seminary-style discussion between the father and son or the teacher and the pupil.
