Earlier quoted context omitted.
So am I wrong to think that by retelling this story, we make him right, thus pushing people who similarly want to be remembered forever without being "wise" to do the same?
Or maybe we're remembering him for giving us a pithy example with an even more pithy punchline that explains in some small way a fundamental part of the human mind? In that way, Hatim al-Tai’s brother was wrong. He was remembered for his wisdom, so much so that I only know of Hatim al-Tai as a way to express this story about his brother.
If the same thing happened but the story wasn't passed on, then it would not have been the right path to reach his goal.
For a modern reference, that is why I'm a strong supporter of not propagating the names of people committing things like mass killings for glory, like we've seen quite a few times.
