Not at all. It is neither against nor required by Stoicism.
Stoicism is broadly compatible with theism, and Neo-Stoicism was a movement specifically about finding common ground between Christianity with Classical Stoicism, rooted in the fact that both developed around the same time and that Seneca's brother had a meaningful interaction with Paul the Apostle described in the Book of Acts.
The Stoics mention Zeus. In The Enchiridion [1], Epictetus says Zeus has fixed his destiny. In this sense Zeus is much like Fate, and the Stoics generally acknowledged fate. There is no implication that what happens to us is "good". Stoicism is about accepting whatever happens and not worrying about it.
