they perform their responsibilities based on the system...
they perform their responsibilities based on the system defined by the Almighty Allah. The only creature that has choice and will is man…he- based on the nature of his creation- is obliged to do his own duty and responsibility or be refrained from it. Based on his choice - performing or not performing his duty - the results will be a success or a failure.
Allah's will wants the worldly life to be a workshop of deeds and actions, as well, as a field of competition for goods (He Who created Death and Life, that He may try which of you is best in deed) (Holy Qur'an: 67:2). Till when these competitions end, since our father Adam till the last creature on earth, then the Day of Resurrection will approach us; the caller will call in a loud voice: (But stop them, for they must be asked) (Holy Qur'an: 37: 24).
There are many questions to be asked: What have you done with your responsibilities? Have you performed them as expected? Why have you performed some and left some others? Have you done them seeking Allah's pleasure or you have done them just for the sake of personal and worldly benefits? And so on…. In a short note, the Almighty Allah has created every creature for a certain purpose and responsibility, and He guided and gave him the ability to discharge that responsibility.
There is no creature, in this world, that doesn't know the responsibility or responsibilities, which he was created for.
The broad universe, with all its earth, water and sky, was brought into being for the purpose of serving man and, likewise, man was charged with the development of the world, it is not a joke or a play (Did ye then think that We had created you in jest) (Holy Qur'an: 23:110), (Does man think that he will be left uncontrolled -without purpose-?) (Holy Qur'an: 75:36) Man without Responsibilities Have you ever thought about a man without responsibility?
Would you think about seeing yourself free from any responsibility in life? Then how would the shape of life be? Indeed, a life that is free from responsibility is just like schools without work and assignments, the students are not feeling any sense of responsibility and law, and therefore, how can studies continue in such a school? And how can the end result be achieved?
And how will we be able to differentiate between a hard working student and a lazy one, a successful one from an unsuccessful student?
