Now if Allah took mankind to task by that which they earn by their deeds, He would not leave a creature on its surface. However, He grants them Respite unto an appointed term. And when their term comes to an end, then, verily, they come to know that Allah is ever Seer of His servants. ('Not leave a creature' - Life on the planet earth exists for and manifests itself in the highest form as the humans (2:30), (35:39)).
