Some times our baser self complains as to why a bad thing has happened to me. It is because of our ignorance that we complain. This is the moral of the story in which Prophet Isa makes a trip with Prophet Khizr, may Peace of Allah Almighty be upon both of them. We have a curtain between us and Allah Almighty's hidden plans. If that curtain is removed we shall see that all that is happening is in our best interest. As an instruction to us mortals the curtain is removed from three incidents that are mentioned in Surah Kahaf.
