It has been recalled through a series of memoirs that one of the prominent characteristics of Imam had been to say hello and greet first. One of companions used to recall that him room in the Dar al-Shafa seminary was next to Imam’s room.
Imam always used to say him hello and acquired his welfare first and he could never surpass Imam in carrying out good jobs and tasks.
(Ayatollah Seyyed Hossein Badla)
