Babu lived in a village of Bangladesh. He was a school-boy. There was a canal on his way to school. An old bridge was over that canal. It was useful to one and all of villagers. Yet none cared for its repair. So one day it broke down and caused a good deal of hardship to the villagers. 

Awais Karni was a well-known saint of Yemen. He had none in the world except his blind and lame mother. So, much of his time was spent in helping her. For their livelihood he used to work as a cowherd at day time. The greater part of the night was spent in prayer and meditation. They were very poor. So he had to fast very often in order to help his poor neighbours.
