What is the religious ruling on a person neglecting their talent and failing to develop it, and what is the ruling on parents who stand as an obstacle to their children developing their talents?

Reading and writing are good talents that should be nurtured and used to serve religion and the nation; this is a form of jihad. Your father is keen on your well-being, and he may not oppose your talent, but he fears that your interest in it might be unfruitful or that it might be used for something other than good. Therefore, you should communicate and discuss with your father with all respect and politeness, and it will become clear to you that there is no disagreement between you.
