A person once heard a pious Muslim say that for the last thirty years he was repenting for a sin and he did not know how Allah will deal with him regarding it?
The listener asked, "What was your sin?"
The pious Muslim said, "I used to have a shop in the Bazaar. One day I heard that the whole Bazaar was burning so I rushed to see my shop. When I reached there I saw that except my shop all the shops were razed to the ground. I thanked God for having saved my shop. But immediately I realized my mistake. How can I call myself a Man when I couldn't feel the loss of my neighbors? That is why I am repenting for that lapse on my part for the last thirty years.”
