There’s a rule in the world, when a man expects something from someone then he also fears that person and if one expects something in return then one tries to make the person (from whom there is expectation) happy. A shopkeeper makes every effort to make the customer happy. People of Imaan were taught through the Ambiya Alayhimussalaam that man has to return to Allah and will be examined for his life (how he spent his life) and then he will be rewarded (accordingly). When this is the worry of a man (being examined after death and rewarded accordingly) it is then that he strives to ensure he does not make Allah unhappy and this is peity (Taqwa).
