Allah has certain sunan (methodoligies) in this life. One of them can be summarized in this famous quote "What Goes Around Comes Around." But as Muslims we take this to the next level as we believe that one of Allah's Beautiful Names is Ad-Dayyan (The One Who Recompenses). So this encourages us to do good and discourages us to do any evil regardless of how small it may be. Enjoy, benefit, get entertained and share the khair.
