Once, a bengali babu went to gulzar to learn shayari..

gulzar sahib asked the bengali babu
to repeat after him:

"na gila karunga,
na shikwa karunga...
tum salaamat raho
is duniya me ,
rab se yahi dua karunga."

the bengali babu repeated:

"na geela korega,
na sukha korega....
tum saala,
mat raho
is duniya me ,
rob se
yehi dua korega"

gulzar fainted ...
