During the days of the Companions of the Prophet (PBUH) the following story took place.
A traveling man was passing by a small garden in his way. Exhausted from the vigorous desert he found a good clean shadowed spot and laid down in the cool breeze. But his camel strayed into the garden eating what ever comes in its way stepping over small vegetables and eating fruits in high trees. As the camel was doing what it does best the owner of the garden walked through the mess in shock. He hit the camel furiously and uncontrollably which caused its death.
The sleeping traveler woke up from the noise. When he saw the other man standing over his dead desert ride; he did not realize his actions until he was fighting with the gardener. It was a bloody fight that ended by the gardener’s death.
The Gardener’s tribe members rushed to the site and took hold of the traveler demanding justice. While they were arguing about the travelers request to go back to his tribe to leave his will and return to receive his punishment; while they were at this, Abu Hurayra, the Companion, heard the loud noises. Abu Hurayra stopped by asking what the argument was about. After Abu Hurayra realized the situation of the traveler being stranded in a strange land wanting to go back to his family to leave his will and may be say his goodbyes; he told the dead man’s relatives that he would grant the man’s return. Of course people honor Abu Hurayra’s word and graciously accepted his offer and they let the man in his way.
Many days later, the man did not return and the dead man’ family became restless. They went to Abu Hurayra asking him in concern how can he guarantee a strange man that he did not know and never seen before. Abu Hurayra said “So it is not said that people of grace are gone.” As he was saying that, the condemned man walked in. Now people are speechless; looking at a man that had his freedom in his hands and he gave away that freedom willingly by showing up again. They could not resist but to ask “What brought you back? We don’t know who you are or where you are from!” The man answered “So it is not said the people of Faithfulness are gone.” Amazed and humbled by what they just witnessed of actions of great morality the relatives of the deceased said “And we forgive you and drop our right. So it is not said that people of Mercy are gone.”
This is how a single good deed can start a chain-reaction of other great actions. I hope from Allah that the reader may benefit from this and start as many good deeds as they are capable of. May Allah reward us all.
