What is the ruling of Islamic law on advocating for "freedom of thought" in the sense of freedom of belief?

Whoever permits freedom of belief, allowing a person to believe in whatever religion they wish, is a disbeliever. This is because religions are revelations from Allah, not mere ideas. In summary, whoever believes that it is permissible for anyone to adopt a religion other than Islam is a disbeliever in Allah, due to His saying: (And whoever seeks a religion other than Islam, it will never be accepted from him).
