Are there any Hadiths or Sharia rulings that prohibit bathing at night or at a late hour, based on the belief that it is disliked in the religion due to Satan and the pouring of hot water?

There is no reprehensibility in performing ghusl (ritual bath) or entering the bathroom at any time, day or night, due to the absence of any legal evidence for reprehensibility, and due to people's need for it. It is disliked to pour hot water in bathrooms or other places, because it may harm the jinn. If a Muslim is compelled to do so, he should say "Bismillah (in the name of Allah)" before pouring the water or entering the bathroom.
