Why did the wealthy man in Chapter 47 disbelieve his wife's dream about donating money?

The wealthy man dismissed his wife's dream due to his skeptical and transactional worldview. As explained in Chapter 47, he questioned the divine logic, wondering why God would communicate through his wife's dream to ask for his money instead of appearing to him directly. He rationalized that the vision was likely false, perhaps caused by disturbed sleep or even a divine ploy to create a 'rift between husband and wife.' He felt his ongoing contributions to the temple renovation were sufficient and viewed his wife's vision with suspicion, ultimately deciding it could not be considered real.
