Is it permissible to work on designing a website for the Buddhist religion?

Muslims believe that any religion other than Islam is false, as Allah states: "And whoever desires a religion other than Islam, it will never be accepted from him," and "Indeed, the religion in the sight of Allah is Islam." Therefore, designing a website that promotes a religion other than Islam, such as idolatry, is forbidden by Islamic law and is considered aiding in disbelief (kufr) and polytheism (shirk). One must refuse to participate in such a venture and advise anyone involved in it.
