Do oral and text message divorces that occurred in the past count, and how should one act in the case of returning to the husband without a fatwa or a new dowry, while feeling uneasy?

If a husband divorces his wife with three pronouncements of divorce, willingly and without coercion, she becomes irrevocably separated from him (Baynunah Kubra). She is not permissible for him again until she marries another husband in a desired marriage and he consummates it with her, and then he divorces her or dies, and her iddah (waiting period) expires. If she returned to him after the three divorces without these conditions being met, the return is invalid, and she is a stranger to him, and she must separate from him immediately. The matter should be presented to a Sharia court or to trustworthy scholars for a ruling.
