A statute of the state of Oz requires all radio stations to set aside one hour of air time per week to be made available without charge for the broadcasting of spiritually uplifting messages produced by recognized religious organizations

Under the Constitution, the Congress shall make no law prohibiting the free exercise (of religion). This is called the free-exercise clause of the First Amendment. The free-exercise clause pertains to the right to freely exercise one's religion. It states that the government shall make no law prohibiting the free exercise of religion.

If a law specifically singled out a specific religion or particular religious practice, under current Supreme Court rulings it would violate the First Amendment. Controversy arises when a law is generally applicable and religiously neutral but nevertheless has the "accidental" or "unintentional" effect of interfering with a particular religious practice or belief.

The free exercise clause of the first Amendment unquestionably provides individuals with the right to freely exercise their religious convictions without the fear of interference or reprisal from the government. The right to religious freedom may be a foundation of protecting individual freedom and independence, of guaranteeing that different religious beliefs and practices get equal protection under the law, and of preventing the government, through constraint or intimidation, from setting up or advancing specific religious beliefs.

I hope this helps. Kindly mark the answer "helpful". Thank you and Best regards.
