What is the ruling on a state whose constitution stipulates the protection of the freedom to perform religious rites and beliefs in accordance with the customs observed in the Kingdom, so long as they do not violate public order or contradict morals?

Islam preserves the rights of non-Muslims by not compelling them to convert and by allowing them to maintain their religion if they live under the protection of Muslims. They are also permitted to practice their own rituals. This does not signify an endorsement of their falsehood, but rather it is an aspect of Islam's leniency, providing them an opportunity to learn about the true religion. If the constitutional text revolves within this sphere, then there is no prohibition in it.
