Does the hatred of some youths for Islamists coming to power, and their fear of the implementation of Sharia – due to its conflict with their personal desires – constitute disbelief, even though they acknowledge the correctness of Sharia rulings and do not deem forbidden things to be permissible?

One must differentiate between a natural dislike for some implications of applying the Sharia (definition), alongside acceptance and submission, and a dislike for what Allah has revealed, denying it, and showing enmity towards it. The former is consistent with the core of faith, while the latter negates one's faith, as Allah Almighty says: {That is because they disliked what Allah revealed, so He rendered their deeds worthless.} A person may naturally dislike a Sharia ruling but accept it religiously. Thus, the soul's natural dislike for something does not contradict its religious acceptance, and its natural love for something does not contradict its religious dislike for it. For example, a Muslim may naturally dislike fighting but accept it religiously because it is a command from Allah. There is no blame on a person if they naturally dislike what has been prescribed for them, as long as it's not due to disliking the command of the Lawgiver. Therefore, what is required is contentment and a cheerful heart. Whoever hates the Prophet's Sharia or a ritual of Islam is a disbeliever. As for one who finds it burdensome without hatred, this indicates a trait of hypocrisy, not disbelief.
