His prayer to God is like a lawyer’s defense of a bad case. Does he argue his case well? What are the points he makes?

Yes, he argued his case very well. He tried every bit to please God with his requests and the recitation of the entire Namaz. He admitted that he made a mistake. He said that he was a good student who was honest and good followers of religion too. He explained his mistake that he wouldn’t have spent his money on jalebis if he had known about the delay in scholarship. Thus, he argues his case like a lawyer.
