Is believing in “signs” haram?

Salam, I’m wondering if believing in signs is haram. For context, I’ve been going through some rough times and prayed to Allah to give me a sign he’s hearing me and listening to me as I was feeling very helpless. I ended up getting a sign that lead me to Surah 12:56. This made me feel at peace as it related to exactly what I’ve been praying for.

Is it haram to take this as a “sign” and believe in it?
