Morteza Ishraqi, a grandson of Imam in other memoirs says that once he passed by Imam while riding on a bicycle.
I fell of the bike while trying to pass by Imam through a narrow pavement, the grandson said.
This is while I had escaped narrowly from hitting Imam with bike.
Imam said nothing and instead of becoming furious helped me in grabbing the bike and asked about my welfare.
