What is the difference between disliking an act of worship and hating it, given that the Prophet, peace and blessings be upon him, said: "Paradise is surrounded by hardships and Hellfire is surrounded by desires," and hardships are what a person dislikes?

The fatwas on the internet clearly state that natural aversion to worship (meaning finding it burdensome because it prevents one from fulfilling desires) is not disbelief (kufr), even though it contradicts what a believer should be like. As for the hatred that constitutes disbelief, it is the hatred of worship as a divine law, i.e., hating Allah's ruling and detesting His law. The first is not disbelief, while the second is disbelief.
